RIFT
the theory that explains continental drift
underwater earthquakes cause
these
where plates move together
where plates move apart
created when magma escapes from between two oceanic plates and cools,
creating a mountain range
created when pieces of crust break off at a divergent
plate boundary (with two continental plates)

BOUNDARIES
CONTINENTAL DRIFT
GEOLOGIC TIME
EROSION
CLIMATE
WEATHER
plates slide past one another
theory proposed by Alfred Wegener that said all the
continents were once together (called Pangaea)
the history of the earth
breaks down landforms by wind,
rain
precipitation and temperature averaged
over long periods of time
the day to day changes in precipitation, temp. etc.
AIR MASS
MARITIME CLIMATE
CONTINENTAL CLIMATE
PREVAILING WINDS
NIGHTTIME SEA BREEZES
DAYTIME SEA BREZES
large pocket of air that takes on the climatic
conditions of the place over which it formed
>1000mm of precipitation and <25oC
temp. range
<1000mm of precipitation and >25oC temp. range
winds that blow in the same direction the majority of the time; Polar Easterlies are an
example
winds blow from the beach to the ocean,
a.k.a. offshore breezes
winds blow from the ocean onto the beach, a.k.a. onshore breezes
CHINOOK
JET STREAM
RELIEF RAINFALL
CONDENSATION
DEW POINT
WINDWARD SLOPE
extremely dry wind that blows from the Rockies to the Prairies in February
large fast-moving current of air, 10 km above the Earth’s
surface
occurs where mountains are close to large bodies of
water
when water vapour turns into a liquid
the temperature at which air cannot hold
anymore water
side of a mountain that faces the wind and
receives the rainfall
LEEWARD SLOPE
RAIN SHADOW
MODERATING EFFECT
SOIL PROFILE
LEACHING
CALCIFICATION
the side of the mountain opposite the wind, does not
receive much rain
on the leeward side of the mountain; dry conditions
places close to water have a small annual temp. range
because water takes longer to warm up and cool down than air
shows the thickness of layers of soil
all nutrients in the soil are carried downwards
by water
in dry conditions, water moves upwards
ECOZONES
PACIFIC RING OF FIRE
UNIFORMITARI-ANISM
WIND
3-CELL CIRCULATION
MODEL
TRENCH
regions determined by human and physical
characteristics and their interactions
region of lots of tectonic activity (earthquakes, tsunamis,
volcanoes); outlines the boundary around the Pacific plate
the idea that all the processes we observe today have always
happened at the same rate
formed when air moves from high to
low pressure
shows the movement of air near the Earth’s
surface
occurs at convergent plate boundary (specifically, when a continental plate meets an
oceanic plate)
TOPSOIL
SUBSOIL
PARENT MATERIAL
OCEANIC PLATE
CONTINENTAL PLATE
CONVECTION CURRENTS
made of lots of humus and decaying organic
material
the middle layer in a soil profile; organic and
mineral rich
the bedrock: material from which the soil is made
the denser, thinner type of plate
the lighter, thicker type of plate
the circular movement of mama: caused the heating at
the core and cooling at the Earth’s surface
SUBDUCTIONwhen an oceanic plate goes underneath a continental
(at a convergent plate boundary)
