Slide 2
The existence of water is essential for life on Earth. Water is
made up of two elements, hydrogen and oxygen. Its chemical formula
is H 2 O. Water has three different states, liquid, solid and gas.
The word water usually refers to water in its liquid state. The
solid state of water is known as ice while the gas state of water
is known as steam or water vapor. Water covers around 70% of the
Earths surface. WATER FACTS
Slide 3
Water from a sea or ocean is known as seawater. On average,
every kilogram of seawater contains around 35 grams of dissolved
salt. The freezing point of water lowers as the amount of salt
dissolved in at increases. With average levels of salt, seawater
freezes at -2 C. Water in the form of ice is found at the polar ice
caps of the planet Mars, some scientists have also suggested the
possibility of liquid water on the red planet.
Slide 4
Pure water has no smell and no taste, it also has a pH level
around 7. While most people know that water boils at 100 C (212 F),
this is at the normal conditions of sea level. The boiling point of
water actually changes relative to the barometric pressure. For
example, water boils at just 68 C (154 F) on the top of Mount
Everest The longest river in the world is the Nile River, it
reaches 6650 kilometers in length.
Slide 5

around........ of the Earths surface. 5.Every kilogram of seawater

Slide 7
The water cycle involves water evaporating (turning into a
gas), rising to the sky, cooling and condensing into tiny drops of
water or ice crystals that we see as clouds, falling back to Earth
as rain, snow or hail before evaporating again and continuing the
cycle. EXERCISE: Look at the picture on the next slide and describe
the water cycle. THE WATER CYCLE
Slide 8
Slide 9
Around 70% of the Earths surface is covered by oceans. Ocean
tides are caused by the Earth rotating while the Moon and Suns
gravitational pull acts on ocean water. The largest ocean on Earth
is the Pacific Ocean, it covers around 30% of the Earths surface.
The Pacific Oceans name has an original meaning of peaceful sea.
OCEANS FACTS
Slide 10
Located to the east of the Mariana Islands in the western
Pacific Ocean, the Mariana Trench is the deepest known area of
Earths oceans. It has a deepest point of around 11000 metres. The
Pacific Ocean contains around 25000 different islands, many more
than are found in Earths other oceans. The Pacific Ocean is
surrounded by the Pacific Ring of Fire, a large number of active
volcanoes. The second largest ocean on Earth is the Atlantic Ocean,
it covers over 21% of the Earths surface.
Slide 11
The Atlantic Oceans name refers to Atlas of Greek mythology.
Amelia Earhart became the first female to fly solo across the
Atlantic Ocean in 1932. The third largest ocean on Earth is the
Indian Ocean, it covers around 14% of the Earths surface. During
winter the Arctic Ocean is almost completely covered in sea
ice.
Slide 12
What is the largest ocean? What is the deepest area of Earths
oceans? Where can we find islands: Madagascar, Seychelles, Sri
Lanka? Where can we find islans: Cook Islands, Tahiti, Hawai,
Galapagos islands? Where can we find islands: Haiti, Barbados, St.
Helena What is the Ring of fire? Look at the next slide. QUICK

Slide 27
The Nile is famous as the longest river in the world. The river
got its name from the Greek word Neilos, which means valley. Only
22% of the river passes through Egypt, the other countries through
which Nile passes are Sudan, Burundi, Ethiopia, Zaire, Kenya,
Eritrea, Uganda, Rwanda and Tanzania. NILE RIVER - FACTS

The Nile Delta in Northern Egypt is where the Nile River drains
in to the Mediterranean Sea. It is around 160 kilometres in length
and spreads out over 240 kilometres of coastline. It is rich in
agriculture and has been farmed for thousands of years. Around 40

The Amazon River is located in South America. It runs through
Guyana, Ecuador, Venezuela, Bolivia, Brazil, Colombia and Peru.
During the wet season, the Amazon River can reach over 190
kilometres in width. There are no bridges that cross the Amazon,
mostly because there is no need, the majority of the Amazon River
runs through rainforests rather than roads or cities. AMAZON RIVER

The largest city along the Amazon River is Manaus. Located in
Brazil it is home to over 1.7 million people. There are over 3000
known species of fish that live in the Amazon River, with more
constantly being discovered. Anacondas lurk in the shallow waters
of the Amazon Basin, they are one of the largest snakes in the
world and occasionally attack larger animals such as goats that get
to close the water. The Amazon River is also home to the piranha, a
meat eating type of fish!
