A LAND OF THOUSAND LANGUAGES

Africa contains well over a thousand languages some have estimated over two thousands, most of african origin & a few of european origin. africa is the most polyglot continent in the world. it is not rare to find individuals there who fluently speak not only several african languages, but one or two european ones as well. there are four major lanugage families native to africa. they are:

- the afro-asiatic languages are a language family of about 240 languages & 285 million people widespread throughout east africa, north africa, the sahel & southwest asia.

- the nilo-saharan language family consists of more than 100 languages spoken by 30 million people. nilo-saharan languages are mainly soken in chad, ethiopia, kenya, sudan, uganda, northern tanzania.

- the niger-congo language family covers much of sub-saharan africa & is propbably the largest language family in the world in terms of different languages. a substantial number of them are the bantu languages spoken in much of sub-saharan africa.

- the khoisan languages number about 50 & are spoken in southern africa by approximately 1,20,000 people . many of the khoisan languages are endangered. the khoi & san peoples are considered the roiginal inhabitants of this part of africa.

following colonialism nearly all african countries adopted official languages that originated outside the continent, although several countries nowadays also use various languages of native origin (such as swahili) as their official language. in numerous countries , english & french are used for communication in the public sphere including government, commerce, education & media.

ANDEAN RANGE

the andean range is composed principally of two great ranges, the cordilera oriental & cordillera occidental, often seperated by a deep intermediate depression, in which arise other chains of minor importance, the chief of which is chile's cordillera de la costa. other small chain arise on the sides of the great chains. the cordillera de la costa, starts from the southern extremity of the continent & runs in northerly direction, parallel with the coast, being broken up at its beginning into a number of islands & afterwards forming the western boundary of the great central valley of chile. to the north this coastal continues in small ridges / isollated hills along the pacific ocean as far as venezuela, always leaving the same valley. this andean range extended over 7 countries. some of them known as andean states itself. the name andes comes from the Quechua word anti, means "high crest". another , it is derived from spanish word "anden" means terrace in reference the culitvation terraces used by the Incas & other related peoples. the andes range is the highest mountain range outside asia, with its highest peak, Aconcagua , rising to 6960 mts (22,841 ft) above sea level. the andes cannot match himalayas in height but do so in width & are more than twice as long. 

ARCHIPELAGO

Page 2: geography short notes

it is a chain or cluster of islands. the word archipelago literally means "chief sea", from greek arkhon & pelagoes. in antiquity , the archipelago was the proper name for the aegean sea & later shifted to islands. archipelago are usually found in the open sea; less commonly , a large land mass may neighbour them. Scotland has more than 700 islands surrounding the mainland. archipelago are often volcanic, forming along mid-ocean ridges but there are many other processes involved in their construction, including erosion & deposition. the 4 largest modern states that are mainly archipelagos are : japan, philippiness, new zealand, indonesia. the largest archipelago in the world by size is in northern canada situated in the artic ocean.

ARETE

it is a thin , knife-like , ridge of rock which is typically formed when the two glaciers erode parallel U-shaped valleys. the Arete is a thin ridge of rock that is left seperating the two valleys.can also form when two glaciers cirques erode headwards towards one another, frequently this results in saddle shapped pass called Col. the edge is sharpened by freeze thaw weathering. the word arete is actually French for fishbone.

Few examples of arete are :- knife-edge on Mount Katandin, maine, USA- clouds rest, in the Sierra nevada, california- the Minarets in sierra nevada, california- the garden wall in glacier national park, wales.- striking edge in the english lake district- the catwalk in olympic national park, washington, USA.

ATOLL

it is an island of coral that encircles a lagoon partially or completely. the word atoll is derived from the Dhivehi an Indo-Aryan language spoken on the Maldives islands word atholhu. its first recorded use in english was in 1625. the term was popularized by charles darwin who described atolls as a subset in a special class of islands.

DEFINITION :

atolls are those as " an annular reef enclosing a lagoon in which there are no promontories other than reefs & islet composed of reef detritus". these are the product of the growth of tropical marine organisms, so these islands are only found in warm tropical waters . volcanic islands located beyond the warm water temperature requirements of reef building organism become sea-mounts as they subside & are eroded away at the surface. islands more polar evolve towards sea-mounts islands more equatorial evolve towards atolls. most of the world's atoll are in PAcific ocean & Indian ocean.

THE BEAUFORT SCALEthis is the scale used for measuring & recording the strength of the wind. it is based on estomated velocity at 10 m (33feet) above the ground. it was devised by admiral sir beaufort, in 1805.

DESCRIPTION = SPEED (KM/HOUR) = POSSIBLE EFFECTSI. LIGHT WINDS :

Page 4: geography short notes

calm = 0 = chimmney smoke rises vertically light air = 1.5-5 = smoke drifts gently light breeze = 6-12 = leaves rustle, wind felt on face. gentle breeze = 13-20 = leaves & twigs on trees move.

II. MODERATE WINDS :DESCRIPTION = SPEED (KM/HOUR) = POSSIBLE EFFECTS

moderate breeze = 21-29 = dust & paper raised from ground fresh breeze = 30-39 = small trees start to sway. strong breeze = 40-50 = large braches move moderate gale = 51-61 = whole trees sway.

III. GALES :DESCRIPTION = SPEED (KM/HOUR) = POSSIBLE EFFECTS

fresh gale = 62-75 = twigs are broken off trees strong gale = 76-87 = slight structural damage to buildings whole gale = 88-102 = trees are uprooted & houses damaged. storm = 103-121 = widespread damage occurs hurricane = above 121 = widespread devastation occurs.

Birds in IndiaBitternIndian bittern is a bird belonging to the Ardeidae family of herons. Almost all the subspecies of Bitterns have a short neck and tend to be more secretive than the other members of the family. Indian Bittern birds form a monophyletic subfamily in the heron family of Botaurinae.

Crested Serpent EagleIndian Crested Serpent Eagle, a member of Accipitridae family, is scientifically known as Spilornis cheela. It is a specialist reptile eater, which mainly hunts snakes and lizards.

Grey FrancolinGrey Francolin, also known as Grey Partridge, is a resident bird of the Indian subcontinent. The species was introduced for the first time in the Andaman Islands. Since then, it has beautifully adapted itself to the country as well as its climate.

Greylag GooseGreylag goose, Anser anser, is one of the Old World species of birds and was known in the pre-Linnean times as Wild Goose. It has ancestral relations with the domesticated geese of Europe and North America. Gray Lag Goose is a very frequent winter visitor to the north regions of the Indian subcontinent.

Great Indian HornbillGreater Indian Hornbill is considered to be the largest member of the hornbill family. Scientifically known as Buceros bicornis, it is usually found inhabiting the forests of Indian

Page 5: geography short notes

subcontinent, the Malay Peninsula and Sumatra, Indonesia. The average lifespan of the Great Pied Hornbill of India exceeds 35 years and may go upto 50 years in captivity.

HeronIndian heron belongs is a member of the large wading bird family, known as Ardeidae. It is found mostly inhabiting the tropical and sub tropical areas. However, Indian herons can also be seen in temperate areas. There is one major characteristic that distinguishes herons from the other birds.

PeacockBlue peacock is regarded as one of the most beautiful birds throughout the world. It is also the National Bird of the Indian subcontinent. Peacock is the name given to a male peafowl, while the female is known as Peahen. Scientifically known as Pavo cristatus (Linnaeus), the Peafowl of India is a swan-sized bird, with a long and slender neck.

Jungle Bush QuailJungle bush quail bird is one of the species of quails found in South Asia. The bird is usually seen in small coveys and is quite shy by nature. One can get a glimpse of the Jungle bush quails of India mainly when they burst out into flight from under the vegetation.

StorkIndian stork is one of the 17 different species of storks found throughout the world. The only continent where storks are not found is that of Antarctica. The natural habitat of the storks comprises of Indian fields, savannas and marshes.

EOLINE PROCESSES

it is the processes pertain to the activity of the winds & more specifically , to the winds ability to shape the surface of the earth & other planets. winds may erode transport & deposit minerals & are effective agents in regions with sparse vegetation & large supply of unconsolidated sediments . this process are important in arid environments such as deserts . wind erodes the earth's surface by deflation , by the removal of loose, fine-grained particles , by the turbulent eddy action of the wind & by abrasion. regions which experience intense & sustained erosion are called deflation zone. most of Eoline deflation zones are composed of the desert pavement, a sheet-like surface of rock fragments that remains after wind & water have removed the fine particulars, a dark, shiny stain called desert vanish is often found on the surface of some desert rocks that have been exposed at the surface for a long period of time. shine stain minerals are manganese, iron oxides, hydroxides, clay. deflation basins , called blowouts are hollows formed by the removal of particles by wind . wind-driven grains abrade landforms. sculpted landforms , called Yardangs, are up ot tens of meters high & kilometers long are form that have been stremlined by desert winds.

Page 10: geography short notes

ERG LANDFORM

an erg is also known as duna sea is a large relatively flat area of desert covered with wind-swept san with little of to no vegetation cover. the term takes its name from the Arabic word erg mean "dune field". an ergis defined as to be a desert area that contains more than 125 square kilometers of eolian sand & where sand covers more than 20% of the surface approximately 85% of the earth's mobile sand is found in ergs that are larger than 32,000 km2. ergs are als found on other celestial bodies, such as venus & saturn's moon titan. erg are concentrated in 2 broad belts between 20 degree-40 degree S latitutdes, which includes regions crossed by the dry, subsiding air of the trade winds. averaged erg are limited to regions which receive not more than 150 mm of annual precipitation. sand sea & dune fields generally occur in regions downwind of copious sources of dry, loose sand, such as dry riverbeds , deltas, flood plains, glacial out wash plains, dry lakes & dry beaches. at least 1 million years are required to build ergs with very large dunes sand sea that have accumulated in subsiding structural & topographic basins, attain great thickness more than 1000m. by nature ergs are very active. individual dunes forming ergs typically have width, length / both dimensions greater than 500m.

ESKER

it is a long , winding ridge of stratified sand & gravel. these are frequently several miles in length, most of esker are believed to form in ice-walled tunnels by streams which flowed within & under glaciers. after the retaining ice walls melt away, stream deposits remain as long winding ridges.it it is also form above the glaciers by accumulation of sediment in supraglacial channels, increvasses, in linear zones between stagnant blocks, the rate of plastic flow & melting of the basic ice determines the size & shape of the subglacial tunnel. this in turn determines shape, composition, structure of Esker. they are no often found as continuous ridges, but have gaps that seperate the winding segments. the ridge crests of eskers are not usually level for very long & are generally knobby. Eskers can be borad-crested / sharp-crested with steepsides. they can reach hundreds of kilometers in high. the concentration of rock debris in the ice & the rate at which sediment is delivered to the tunnel by melting & from upstream transport determines the amount of sediments in Eskers. the sediments consists of coarse-grained, water-laid sand & gravel. cross-bedding is common in Esker.

the name Esker is derived from Irish word eiscier means " a ridge of one seperating two plains surfaces". the mason esker at 22 miles is one of the longest Esker in the US.

FACTS OF RHINE

Introduction :Rhine is the of the largest at river in Europe. it runs for over 1300 kilometers from its source in South Rhine flows on through France, Germany & Netherlands.* back bone of Europe = Rhine* Rhine originates from = Gothar* Rhine enters rift valley at = Basle* Rhine drains into = North sea* Tributaries of Rhine = Mosel, main, Lippe.

international co-operation over the river Rhine goes back to 1887 with a treaty prohibiting the discharge of wastes dangerous to fish. international commission for the protection of the Rhine against pollution was formed. most recently, after a serious incident in 1986, the Rhino Action Programme was developed , by the 2000, programme aims to achieve a return to the river species such as the salmon which once thrived them. the use of the river of extracting drinking water is also dafeguarded.

The specific aimes of the Rhine Action Programme Approved by a confluence of ministers on the protection of the Rhine against Pollution, in Strasbourg in 1987 are :

- to accelerate the reduction of permanent pollution from all sources.- to reduce the risk of accidents & spillages.- to improve hydrological & other conditions of the river.

At The National Rivers :

- national laws are made starting how much waster material can be discharged.- industrial plants are obliged to have a permit for their emissions.- pollution taxes are imposed on individuals & industrial plants- purification & measuring stations are built.

At International Level :

- there is nore co-operation between countries that share the Rhine- there is an alaram system for every time the concentration of a certain material exceeds its permitted value.- plans are made for the conservation & restoration of natural landscapes.

FELDSPAR

Page 12: geography short notes

it is the name of a group of rock-forming minerals which make up as much as 60% of the earth's crust. crystallize from magma in both intrusive & extrusive rocks, & they can also occur as compact minerals as veins & are also present in many types of metamorphic rock . rock formed entirely of plagioclase Feldspar is known as northosite. they are also found in many types of sedimentary rock. it is typically reddish / pale pink in color, & has a hardness of 60 the mohs scale.

feldspar is derived from the german word feld, field, spat ; a rock that does not contain ore. feldspar refers to minerals that contains feldspar.

COMPOSITION : this group of minerals consists of framework or tectosilicates . composition of major elements in common feldspar can be expressed in term of 3 endmembranes.

K-feldspar endmembranes = KAlSi3O8Albite endmembranes = NaAlSi3O8Anorthite endmembranes = CaAl2Si2O8

- sodium solution between K-feldspar & albit are called alkali feldspar. - solid solution between albite & anorthite are called plagioclase.- sanidine, orthoclase, microline refer to polymorphs of K-feldspar.

- sanidine is stable at the highest temperature - microline at the lowest perthite is typical texture in alkali feldspar, due to exsolution of contrasting alkali feldspar compositions during cooling of an intermediate composition. the perthitic texture in the alkali feldspar of many granites are coarse enough to be visible to the naked eye.

USES :- feldspar is common raw material in the production of ceramics.- feldspar are used for thermoluminescence dating & optical dating in earth science & archeology.- feldspar is often an anti-eating agent used in powedered forms of non-dairy creams.

FLASH FLOOD

it is rapidly flooding of geomorphic lowlying areas- washes, rivers & streams -- caused by the intense rainfall associated with a thunder strom, or multiple thunder storms. they are distinguished from a regular flood by a timescale less than 6 hours.

CAUSES

it occurs when the ground becomes saturated with water that has fallen too quickly to be absorbed. they mostly often occur in dry areas that have recently received precipitation, these are extremely dangerous because of their sudden nature.

Page 13: geography short notes

FOEHN WIND

this occurs when a deep layer of prevailing wind is forced over a mountain range. as the wind moves upslope, it expands & cools, causing water vapour to precipitate out. this dehydrate air then passes over the crest & begins to move downslope. Foehn winds can rise temperature by as much as 30 degree C , 54 degree F in just a matter of hours.

EFFECTS :

winds of this type are called "snow-eaters" for their ability to make snow melt rapidly. this ability is based not only on high temperature, but also the low relative humidity of the air mass. Foehn winds are often associated in popular mythology with illness ranging from migraines to psychosis.

the name Foehn came from German, originated in the alpine region.

Foehn winds are called in different names in different countries. they are :- Zonda winds in Argentina- Chinook in USA & Canada- the Nor'Westr in Hawkes Bay- Halny in Carpathian Mountain, Eastern Europe- Fogony in the Catalan Pyrenees- Berg wind in South Africa- Viento Sur in the Cantabrian region of North Spain- Terral in Malaga Souhtern Spain- Foehn wind in Austria, southern germany.

FUMAROLE

it is an opening in earth's crust , often in the neighbourhood of volcanoes, which emits steam & gases such as carbon dioxide, sulfur dioxide, hydrocloric acid & hydrogen sulfide. the name solfatare , from the italian solfa sulfur, is given to fumaroles that emit sulfurous gases.fumarole may occur along tiny cracks or long fissures, in chatic clusters or fields & on the surface of lava flows & thick deposites of pyroclastic flows. a fumarole field is an area of thermal springs & gas vents are releasing gases or interacting with groung water from the perspective of ground water. fumarole could be described as a hot spring that boils off call its water before the water reaches the surface example famous ot spring that boils off call its water before the water reaches the surface example famous valley of ten thousand smokes , which was formed during the 1912 erruption of novarupta in alaska.

GEYSER

Geysers were named after a famous "the Great Geysir" of Iceland. That is located around the northwest area of Mt. Hekla, which is also an active volcano in the south central part of the island. That means "roarer" in Icelandic language.

It is a type of hot spring that errupts periodically, ejecting a column of hot water & stream into the air. the name geyser comes from geysir, the name of an errupting spring at Iceland. the word comes from Iceland means "to gush". the formation of geysers require a favourable hydrogeology which exists in only a few places on earth, so they are fairely ran phenomena. about 1000 exist worldwide, half of them is in Yellowstone National Park, US. geyser erruptive may change / cease due to ongoing mineral deposition with in the geyser as plumbing, exchange of functions with near by hot springs, earthquakes influence. geyser activity all hot spring activity is caused by surface water gradually

Page 15: geography short notes

seeping down through the ground until it meets rock heated by magma. geyser differ from non-eeruptive hot springs in their subterranean structure.

The geysers are made by a forceful eruption of water to go to heights of 100 to 200 feet, and the record holding is around 1500 feet. When the water comes to blow off steam, which is responsible for all that roaring. The vigor of these eruptions is what we want to understand more of. Geysers are always around places like hot springs, but then they are a rather unusual phenomenon.

TWO TYPES OF GEYSERS :

1. FOUNTAIN GEYSER :errupt from pools of water, typically in a series of intense, even violent, burts.

2. CONE GEYSER :these geysers which errupt from cones of siliceous sinter, usually in steady jets that last anywhere from few seconds to several minutes.

most geysers form in places where there is volcanic rhyolite rock which dissolves in hot water & forms mineral deposite called silicons sinter. many geyser have been destroyed by people throwing litter & debris into them. others have ceased to errupt due to the dewatering by geothermal power plants. the specific colours of geysers derices from the fact that despite the apparently harsh condition, life is often found in them in the form of thermophilic prokaryotes. in the 1960s , when the research of biology of geyser first appeared, scientists were generally convinced that no life can survive above around 73 degree c (163 degree F). the upper limit for the survival of eyanobacteria , as the structure of key cellular proteins & DNA would be destroyed.

Other Physical Nature

In the Earth where there is an opening that would contain superheated water that periodically erupts in a shower of water and of steam. They are found around places where there are heated rocks close to the surface. Iceland is located on the Mid Atlantic ridge noted for its basic activities. Old Faithful is known to be the most famous geyser in Yellowstone National Park, Old Faithful is not the largest geyser in Yellowstone, but is known to be the most frequent on its eruptions on time periods. These eruptions do erupt in about 45 to 110 minutes, with an average of 76 minutes less predictable. However most geysers are always irregular, though Old Faithful ejects 14,000 to 32,000 liters of boiling water to heights of aver 30 to 55 m in each eruption. Approximately 700 geysers, Yellowstone has 500 of all the geysers in the world. Once the other geysers in the Norris Geysers the north Geysers Basin did erupt to 12 to 15 m every 60 seconds.

GLACIER ERRATIC

it is a piece of rock that deviates from the size & type of rock native to the area in which it rests; the

Page 16: geography short notes

name "erratic" is based on the errant location of these boulders. these rocks were carried to their current location by glacial ice, over hundred's of kilometers. Erratics can range in size from pebbles to large boulders such as Big rock which is 16,500 ton is in Alberia.

How can ozone be both good and bad?The thing that determines whether ozone is good or bad is its location.

Ozone is "good" when it is in the stratosphere. The stratosphere is a layer of the atmosphere starting at the level of about 6 miles (about 10 kilometers) above sea level. The stratosphere naturally contains about six parts per million of ozone, and this ozone is very beneficial because it absorbs UV radiation and prevents it from reaching us.Ozone is "bad" when it is at ground level. Ozone is a very reactive gas that is hard on lung tissue. It also damages plants and buildings. Any ozone at ground level is a problem. Unfortunately, chemicals in car exhaust and chemicals produced by some industries react with light to produce lots of ozone at ground level. In cities, the ozone level can rise to a point where it becomes hazardous to our health. That's when we hear about an ozone warning on the news.

Introduction India

Background: The Indus Valley civilization, one of the oldest in the world, dates back at least 5,000 years. Aryan tribes from the northwest invaded about 1500 B.C.; their merger with the earlier Dravidian inhabitants created the classical Indian culture. Arab incursions starting in the 8th century and Turkish in the 12th were followed by those of European traders, beginning in the late 15th century. By the 19th century, Britain had assumed political control of virtually all Indian lands. Indian armed forces in the British army played a vital role in both World Wars. Nonviolent resistance to British colonialism led by Mohandas GANDHI and Jawaharlal NEHRU brought independence in 1947. The subcontinent was divided into the secular state of India and the smaller Muslim state of Pakistan. A third war between the two countries in 1971 resulted in East Pakistan becoming the separate nation of Bangladesh. Despite impressive gains in economic investment and output, India faces pressing problems such as the ongoing dispute with Pakistan over Kashmir, massive overpopulation, environmental degradation, extensive poverty, and ethnic and religious strife.

Economy India

Economy - overview:

India's diverse economy encompasses traditional village farming, modern Agriculture, handicrafts, a wide range of modern industries, and a multitude of services. Services are the major source of economic growth, though two-thirds of the workforce is in agriculture. The UPA government has committed to furthering economic reforms and developing basic infrastructure to improve the

Page 30: geography short notes

lives of the rural poor and boost economic performance. Government controls on foreign trade and investment have been reduced in some areas, but high tariffs (averaging 20% in 2004) and limits on foreign direct investment are still in place. The government has indicated it will do more to liberalize investment in civil aviation, telecom, and insurance sectors in the near term. Privatization of government-owned industries has proceeded slowly, and continues to generate political debate; continued social, political, and economic rigidities hold back needed initiatives. The economy has posted an excellent average growth rate of 6.8% since 1994, reducing poverty by about 10 percentage points. India is capitalizing on its large numbers of well-educated people skilled in the English language to become a major exporter of software services and software workers. Despite strong growth, the World Bank and others worry about the combined state and federal budget deficit, running at approximately 9% of GDP. The huge and growing population is the fundamental social, economic, and environmental problem. In late December 2004, a major tsunami took nearly 11,000 lives, left almost 6,000 missing, destroyed $1.2 billion worth of property, and severely damaged the Fishing fleet.

LAHAR

it is a type of mudflow composed of pyroclastic material & water that flows down from a volcano, typically along a river valley, the term lahar originated in the Javanese language of Indonesia. lahars have the consistency of concrete. fluid where moving then solid when stopped. lahars are be huge, the osceola lahar produced 5600 years ago by mount rainier in washington produced a wall of mud 140 mts 450 feet deep in the white river canyon & extends over an area of over 330 square kilometers. these are extermely dangerous, became of their energy & speed. large lahares can flow several dozen meters per second & can flow for many kilometers , causing catastrophic distruction in their path. lahars possible causes : - snow & glaciers can be melted by a pyroclastic flow during an eruption.- a flood caused by a glacier, lake breakout & heavy rainfall can release a lahar also called glacier run. lahars are associated with volcanic activity, can occur even without any current volcanic activity , as long as the conditions are right to cause the collapse & movements of mud originating from exisitng volcanic ash deposits.

LAMPROPHYRE

it is a greek word Lampros meaning "bright", Prophyre meaning "rocks". they are uncommon, small volume ultrapotassic igneous rocks primarily occuring as dikes, lopoliths, laccoliths, stocks & small instrusions. they are alkaline silica-undersaturated , ultramafic rocks with high magnesium oxide, >3% potassium, high sodium oxide & high nickle & chromium. they occur in all geologic eras.

ESSENTIAL COMPONENTS OF LAMPROPHYRE :

Page 39: geography short notes

- high depth of melting which yields more mafic magmas.- low degrees of partial melting, which yields magmar rich in the alkalies (potassium mainly)- lithophile element (K, Ba, Cs, Rb) enrichment , high Ni & Cr.- high potassium & sodium concentrations.- some form of volatile enrichment, to provide the biolite (phlogopite) & amphilobole (pargasite) mineralogy.- lack of fractional crystallisation- high Mg# (NgO// FeO+Fe2O3).

Lamprophyre are usually associated with voluminous granodiorile intrustive episodes ^. Lamprophyre are also known to be spatially & temporarily associated with gold mineralisatio

MEANDER

it is a bend in a river also known as an oxbow loop. a stream or river flowing through a wide valley or flat plain will tend to form a meanding stream course as it alternatively erodes & deposits sediments along its course . the result is snaking pattern as the stream meander bock & forth across its flood plain . meander is linked to the existance of pool-riffle sequence where meander form hard rock, when the meander meets the hardrock it then bends into another area. on the inside of menader, most of meander occur in the lower course of river . on the inside meander, willows are often far from the bank, whilst on the outside of the bend, the roots of the willows are often exposed & undercut, eventually leading the trees to fall in the river. the term derives from the river known to the ancient greeks Maiandros meander is located in present-day Turkey near the ancient greek town of miletus. Meander is calculated as the length of the stream divided by the length of the valley.

MERCALLI INTENSITY SCALE

it is a scale used for measuring the intensity of an earthquake. the scale quantifies the effects of an earthquake on the earth's surface , humans, objects of nature & man-made structures on a scale of 1 through 12, with 1 denoting a weak earthquake, 12 denoting : one that causes almost complete destruction.

EVOLUTION

it originated with the widely used simple ten-degree rossi-forel scale, which was revised by Halian volcanologist Giuseppi mercalli in 1883 & 1992. in 1902, ten-degree mercalli intensity scale was expanded to 12 degrees by Italian physicist Adolf cancani. it was later completely re-written by german geophysicist August heinrich sieburg & became known as the mercalli-cancani-scale. then changed the name to mercalli-intensity-scale.

MESA ROCKS

this is a spanish & portuguese word meaning table. it is a elevated area of land with the flat top & sides that are usually steep cliffs. it is in table top shape. Mesa form in area where horizontally layered rocks are uplifted by tectonic activity. the differences in strength of various rock layers is what gives mesas their distinctive shape. less resistant rocks, are eroded away on the surface into valley. where they collect water drainage from the surrounding area, while they more resistant layers are left standing out. a large area of very resistant rock, such as sill may shield the layers below it from erosion while the softer rock surrounding it is eroded into valley. thus forming caprock. difference in rock type also reflect on the sides of mesa, as instead of smooth slopes, the sides are broken into a staircase pattern calle "cliff &-bench topography".

Nebraska Sand Hills!SAND HILLS OF NEBRASKA

sand hill is a region of mixed grass prairie in north-central Nebraska, covering just over 1

Page 45: geography short notes

quarter of the state. the region is variously defined by different organizations . so its size is indicated as 19,000 mi2 (50,700 km2) or 23,600 mi2 (61,100 km2). dunes in sand hills may exceed 330 feet (100m) in height. the average elevation of the sand hills region gradually increases from about 1500 feet 550m in the eat to about 360 feet 1100m in the west. the sand hill sit top the massive ogallala aquifer & marshes & shallow lakes both temporary & permanent--are common in low-lying parts of the sand hills. the eastern & central sections of the regions are drained by tributaries of the long river & the niobrara river . the worldwide fund for nature designated the sand hills as an ecoregion, distinct from other grasslands of the great plains. as much as 85% of the sand hills ecoregion is intact naural habitat, the highest level in the great plains. the reason is primarily due to lack of agriculture,. the plant-anchored dunes of the sand hills were formed at the most recent ice age by wind-blown particles originating from regions to the north & west of Nebraska.

NorthWest Passage Opens

the north-west passage - a long-sought short cut between Europe & Asia that has been historically impassable-is opening up due to raising global temperature. this area covered by sea ice in the Arctic region has now shrunk to its lowest level.

- the McClure Strait, the most direct route of the Northwest Passage, has been fully open since early August 2007. there has been a reduction of the ice cover over the last 10 years of about 1,00,000 sq.km per year on average so drop of 1 million sq.km in just one year is extreme.

- these are highly vulnerable to raising temperatures & predicted arctic would be virtually ice free by the summer 2070.

 NUNATAK

it is the exposed summit of a ridge , mountain / peak not covered with ice snow within an icefield or glacier. the term is typically used in areas where a permanent ice sheet is present . nunatak are generally angular & jagged because of freeze. than weathering, & can be seen to contrast strongly with the softer contours of the glacially eroded land below if the glacier retreats. the word nunatak is of grenlandic origin meaning a hill . it has been used in western european languages since 1870s.

PLAGIOCLASE

it is very important series of tectosilicate minerals within the fields par family. rather than referring to a particular mineral with a specific chemical composition, plagioclase is a solid solution series, more properly known as plagioclase feldspar series from greek word "oblique fractor" in reference to its two cleverage angles. the series range from arbite to anorthite endmembers where sodium & calcium atoms can substitue for each other in the mineral crystal lattice structure. plagioclase is a hand samples is often by its polysynthetic twinning or 'record-froove' effect. plagioclase is major constituent mineral in earth's crust. & is consequently an important diagnostic tool in petrology for identifying composition, origin & evolution of igneous rocks.

is named from latin albus, in reference to its unusally pure white color. it is relatively common & important rock-making mineral associated with the more acid rock types & in pegmatite dikes, often with rare minerals like bery & tourmaline.

Page 48: geography short notes

ANORTHITE

was named by the Rose in 1823 from the greek meaning oblique, referring to its triclinic crystallization. anorthite is characteristic of the mafic igneous rocks such as gabbro & basalt.

OLIGOCLASE

is common in granite, syenite, diotire & gneiss. it is frequent associate of orthoclase. the name oligoclase is derived from the greek for little & fracture in reference to the fact that its clevage angle differs significantly from 90 degree. sunstone is mainly oligoclase with flakes of hematite.

ANDESINE

is a characteristcs mineral of rocks such as diorite which contain a moderate amount of silica related volcanics such as andesite.

LABRADORITE

is the feldspar of the more basic rock types such as divrite, gabbro, andesite. basalt is usually associated with one of the pyroxenes. labradorite frequently shows an iridescent disply of colors to light refracting within the lamellae of the display.

BYTOWRITE

named after the former name of Ottawa, Canada. it is rare mineral occasionally found in more basic rocks.

Polynesia!POLYNESIA

Polynesia is generally defined as the islands within the polynesian triangle. the term "polynesia", meaning many islands, was first used by charles de brosses in 1756, & originally islands of the Pacific. jules dumont d'uvrille in 1831 a lecturer to the geographical society of paris proposed a restriction on its use. geographically , & oversimply, polynesia may be described as triangle with its corners at hawaii, aotearoa (new zealand) & rapu nui (easter island). the other main island groups located within the polynesian triangle are samoa, tonga, the various island chains that form the cook islands & french polynesia. nuie is a rare solitary island state near the centre of polynesia. polynesian island groups outside this great triangle include tuvalu & french territory of wallis & futuna. rotuma in the

Page 49: geography short notes

northern fijian islands & some of the lau group to fiji's southeast have strong polynesian character too. in essance, it is an anthropological term referring to one of the three parts of Oceania whose pre-colonial generally belongs to one ethno-cultural family as a result of centuries of maritime migrations.

RIVER REJUVENATION

river is to be rejuvenated when the base level that is flowing down to, is lowered. this can happen by uplift of land, or by a sea or lake that it is flowing into becoming lower. that makes the river suddenly

Page 51: geography short notes

start eroding its bed vertically faster as it gains gravitational potential energy. that causes effect such as meanders cut down as gorges, steps where river suddenly starts flowing faster, & terraces derived from old floodplains. Rejuvenation terrains usually have complex landscape, because remnants of older landforms are locally preserved. parts of flodd pains may be preserved as terraces along the downcutting stream channels. Meandering streams often become entrenched , so a product of older river system is found with step, very pronounced "V" shaped valley. Rejuvenation result from causes which are dynamic, eustatic / static in nature.

I. DYNAMIC : dynamic rejuvenation may be caused by the epeirogenic uplift of a land mass. there movements are either associated with neighbouring orogenic movements.

II. EUSTATIC : this rejuvenation results from the causes which bring worldwide decrease in sea level, & 2 types of such rejuvenation are recognized.

DIASTROPHIC EUSTATISM : it is the change in sea level due to variation incapacity of ocean basins.

GLACIO-EUSTATISM : is the change in sea level due to withdrawal of water into the oceans occupying the accumulation of successive ice sheet.

CHANGES OF STATIC :- decrease in land- increase in runoff because of rainfall- increase in stream volume through acquisition of new drainage by stream diversion

SCORIA

it is a textual term for macrovesicular volcanic rocks ejecta. it is commonly , but not exclusively basaltic in composition. scoria is light as a result of numerous macroscopic ellipsoidal vesicles but most scoria has a specific gravity than 1 & sinks in water. the vasicularity results from the exsolution of magnetic volatiles prior to chilling. scoria differs from purnice in having layer vesicles & thicker vesicles walls, & hence is typically darker in color. it is generally dark brown, dark red, dark black. the word comes from greek skoria means "rust". as raising magma encounters lower pressures, dissolved gasses are able to exsolve & form vesicles. some of the vesicules are trapped when the magma chills & solidifies. vesicules are usually small, spheroidal & donot impringe upon one another, it is formed from a thin layer of froth occuring on some basaltic lava flows due to the bursting of vasicle walls. the thin glass threads are the inter-section of burst vehicles. this is the lightest rock on earth with its specific gravity less than 0.3.

SILLIMANITE

it is also called as Bucholzite . is ia an alumino-silicate mineral with chemical formula Al2SiO2. it is named after American Achemist Brjamin silliman (1779-1864). it is one of the three alumino-silicate : polymorphhs, kyanite & andalusite. a common variety of sillimanite is known as fibrolite, so named because the mineral appears like a bunch of fibres twisted together when viewed under this section or even naked eye. both the fibrous & traditional forms of silicate are common in metamorphosed sedimentary rocks . it is an index mineral indicating a high degree of metamorphtism. sillimanite has been found in brandywine springs, new castle country, delaware, usa. it is also known as rock creek shear zone with the piedmont physiographic provience.

Do rivers always flow from the north to the south?While some oblivious people think that rivers always flow from the north to the south (a term some even call downhill!) but rivers always flow with gravity (unless modified by humans). There are countless examples of rivers that flow from the south to the north (in both hemispheres), such as the Ob in Russia and the Mackenzie in Canada.An interesting analogy was brough up in the Geography Forum - would you fly to Seattle, rent a car, and coast all the way to Los Angeles? Just because south is at the bottom of the map, doesn't mean it's lower in elevation.

How many active volcanoes are in the world?There are approximately 1,500 active volcanoes worldwide.A volcano is considered active if it has erupted in the last 10,000 years. Over 75% of the world's volcanoes and most active volcanoes are located in the Pacific Ring of Fire.

What are the seven seas?Although seamen of long ago are popularly known to have stated "I've sailed the seven seas," there really wasn't a good definition of those seas. However, today

How many tectonic plates are on earth?There are dozens of tectonic plates on earth but only about one seven huge plates. The largest include the African Plate, Antarctic Plate, Eurasian Plate, Indo-Australian Plate, North American Plate, Pacific Plate, South American Plate

How do you convert snow into rainfall amounts?Since precipitation is generally measured in inches of liquid water and not in snowfall

Page 53: geography short notes

amounts, snow is usually converted into inches of water by dividing by 10. Thus, ten inches of snow is equivalent to one inch of rain.Light and loose snow takes more than 10 inches to make an inch of water but dense and slushy snow takes less.

What effect does the Coriolis force have upon my bathtub?It's granted that the Coriolis effect has an affect on the circulation of air and water on the planet but many people also think that the force has an effect on sinks, wash basins, toilets, bathtubs and other tiny bodies of water.Unfortunately, small bodies of water are not affected by the Coriolis effect or bearing on whether sinks and toilets drain in one direction in the Northern Hemisphere and another direction in the Southern Hemisphere

How often does a 100-year flood occur?Large floods are often given designations as a "one-hundred-year flood" but a 100-year flood does not mean that such a flood occurs once every 100 years; instead it means that there is a one in one-hundred (or 1%) chance of such a flood occurring in a given year.Two 100-year floods could occur a year apart or even a month apart -- it all depends on how much rain is falling or how quickly the snow melts. A "20-year flood" has a one in twenty (or 5%) chance of occurring in a particular year so it would be a less destructive flood than a 100-year flood while a "500-year flood" has a one in 500 (0.2%) chance of occurring so it would be much more catastrophic than a 100-year flood.

STACK

It is a geological land form consisting of a steep & often vertical column / columns of rocks in the sea near coast.

Stacks are formed when a part of a headland is eroded leaving small island. They are also form when natural arch collapses due to sub-aerial processes & gravity.

A stack may collapse / be eroded leaving a stums. Stacks forms most commonly on chalk cliffs, beacause of the medium resistance to erosion.

Cliffs with weaker rock such as clay tend to stump & erode too quickly to form stacks, while harder rocks such as granite erode in different ways. stacks are often important sites for nesting seabird.

It is also famous for rock climbing.

SUPER VOLCANO

it is a volcano that produces the largest & most voluminous kinds of erruption on earth. the explosivity of such eruptions varies, but the volume of ejected tephra is enough to radically alter the landscape & severely affect global climate for years, with cataclysmic consequences for life. the term originally coined by the producers of the BBC popular science program, horizon. in the year 2000 it refered to three types of eruption. a large igneous province is an extensive region of basalts on a continental scale, resulting from flood basalt eruptions. when created regions often occupy several million km2 & have volumes on the order of 1 million km3. eruptions with a volcanic explosively index of 8are mega- colossal events that eject at least 1000 km3 of pyroclastic material. VEI-8 eruptions are so powerful that they form circular calderas rather than montains because the downward collapse of land at the eruption site fills empited space in the magma chamber beneath. the caldera can remain for millions of years after all volcanic activity at the site has ceased.

Page 62: geography short notes

ERUPTIONS : - lake tarpo, nothr island, new zealand - oruanui eruption - 26,500 years ago , 1170 km3

- lake toba , sumatra, indonesia - 75,000 years ago , 2800 km3

- la garita caldera, colorada, us, - 2.2 million years ago , 2500 km3

lake toba eruption plunged the earth into a volcanic winter, eradicating an estimated 60% of human population & was responsible for the sulphuric acid in the atmosphere.

SYNOPTIC SCALE METEOROLOGY

it is also known as cyclonic scale. it is a horizontal scale of order of 1000 kilometers / more this corresponds to a horizontal scale typical of mid-latitudes depressions. most high & low pressure are as seen on weather maps are synoptic scale systems. the word synoptic is derived from the greek word sunoptikos meaning seen together.

TOMBOLO

it is a deposition landform such as a spit or bar which forms a narrow piece of land between an island or offshore rock & a mainland shore; / between two islands. they usually form because the island causes wave refraction, depositing & shingle moved by longshore drift in each direction around the island where the waves meet eustatic sea level rise may also contribute to aceretion as material is pushed up with rising sea levels.

********************************

VENTIFACT

Page 65: geography short notes

these are rocks that have been abraded, grooved, by wind-driven sand. these gemorphic features are most typically found in & environments where there is little vegetation to interfere with eolian particle transport where there are frequently strong winds, & where there is a steady but not overwhelming supply of sand. ventifacts can be abraded to eye-catching natural sculptures. in moderately tall, isolated rock out crops, mushrooms shaped pillars of rock may form as the out crop is eroded by saltating sand grains. this occurs because , even in strong winds, sand grains can't be continuously held in the air.

WADI

It is traditionally a valley. In some cases it can refer to a dry river bed that contain water only during times of heavy rain. The wadi is very widely found in arabic to ponyms were streams in a desert environment & generally are dry year round except after rain. The deposition of wadi is rapid because of the sudden loss of the velocity & absorption of the water into the ground.

Why was the Prime Meridian established at Greenwich

In 1675, the Royal Observatory at Greewich, outside of London was created to study the determination of longitude (a vital comonent to oceanic navigation). The United Kingdom and, by association, the United States, used Greenwich as the reference point for longitude. Thus, by the time of an international conference in 1884 to establish fixed degrees of longitude on the planet, many countries had been using Greenwich as the Prime Meridian for decades so the tradition became internationally accepted

World Largest Coral Reef!GREAT BARRIER REEF - WORLD'S LARGEST CORAL REEF SYSTEM

it is the worlds largest coral reef system, composed of roughly 3000 individual reefs & 900 islands stretching for 2600 km over an area of approximately 3,44,400 square kilometers. the reef is located in the coral sea, off the coast of Queensland in northeast australia. Great Barrier Reed can be seen from outer space & is worlds biggest single structure made by living organism. this is build by billions of tiny organisms , known as coral polyps. when coral sea basin was formed, coral reef began to grow in the basin until about 25 million years ago, they can increase in diameter from 1-2 cms per year & grow vertically any where from 1-15 cms per year. they are limited to growing above a depth of 150 meters due to their need for sunlight & cannot grow above sea level. the land formed the subtrate of the current great barrier reef was a coastal plain formed from the eroded sediments of the great dividing range with some larger hills from 20,000 years ago until 60,000 years ago, the sea level rose steadily. by around 13,000 years ago the sea level was 60 meters lower than the present day, corals began to grow around the hills of the costal plain , which were by then, continental

Page 66: geography short notes

islands. this GBR supports a diversity of life, including many vulnerable & endangered species, some of them are endamic to the reef system. there are thirty species of whales, dolphines , porpoises have been recorded in the GBR, including the dwarf minke whale, indo-pacific humpback dolphin & the humpback whale. large populations of dugongs live there. six species of a sea turtles come to the reef to breed-the green sea tutle, leather back the sea turtle, hawksbill turtle, loggeshead sea turtle, olive ridly. salt water crocodiles live near the reef.

Xenolith!XENOLITH

it is rock fragment which becomes enveloped in a larger rock during the latter's development & hardening. in geology xenolith is almost used to describe igneous rock during magma emplacement & eruption. xenolith may be engulfed along the margins of magma chamber, torn loose from the walls of an erupting lava conduct / explosive diatreme along the base of a flowing lava on earth's surface. xenolith provide information about the composition of the innacessible mantle, basalts, kimberlites, lamproites which have their source in the upper mantle. often contain fragments & crystals assumed to be a apart of the originating mantle minualogy.

Yardang!YARDANG

It is a wind-abraded ridge found in cohesive material. The word is derived from turkish meaning, 'steep bank'. Some are found in dried-up river beds. These are elongate features typically 3 or more times longer than they are wide, when viewed from above , resemble the hull of a boat.

TYPES:a) Mega-yardang : can be several kilometers long & hundreds of meters high.

b) Meso-yardang : these are generally a few meters high & 10-15 meters long.

c) Micro-yardang : these are only few centimeters high.

Yardang form in environment where water is scarce. The prevailing winds are strong, unidirectional & carry an abrasive sediment load. A large concentration of mega are found near the tibesti mountains in the central sahara. There is a famous yardang are 'hole in the rock' in papayo parla in phoenix, arzona , a rock formation with a roughly another yardang arizona is window rock, near the town of window rock. It is a 200 feet sandstorm hill with a very large
