Page 2
The processes by which granite breaks down to
sediment.
Page 3
What are Erosion and Weathering?
Page 4
The type of rock that INTENSE PRESSURE
creates.
Page 5
What is Metamorphic?
Page 6
Slate become this when it is heated.
Page 8
Limestone, chalk and sandstone are this type of
rock that form from sediments.
Page 9
What is Sedimentary rock?
Page 10
These are rocks that solidified directly from molten silicates (i.e., magma). Examples are granite, basalt, pumice and
flint.
Page 11
What is Igneous rock?
Page 12
This is Canada’s oldest landform.
Page 13
What is the Canadian Shield?
Page 14
The Rocky Mountains are found in this landform.
Page 15
What is the Western Cordillera?
Page 16
This landform is Canada’s oldest Highland landform.
Page 17
What is the Appalachian Highlands?
Page 18
This western landform has deep fiords.
Page 19
What is the Western Cordillera?
Page 20
This landform has the nickname
“Canada’s Heartland.”
Page 21
What is the St. Lawrence
and Great Lakes Lowlands?
Page 22
The temperature is about 4,800OC. The pressure is over 3.6 million times the pressure
at the Earth’s surface. Gravity is ZERO.
Page 23
What is the centre of the Earth?
Page 24
Wegener proposed this theory to explain the shape of
the Earth’s land masses.
Page 25
What is Continental Drift?
Page 26
One large land mass
Page 28
The movement of the Earth’s plates by
convection currents in the semi-molten layer of the
Mantle
Page 29
What is Plate Tectonics?
Page 30
Constantly changing due to forces such as erosion and deposition, this outermost
layer of the Earth is between 6 and 100 km thick.
Page 31
What is the Crust?
Page 32
Called the Age of Mammals, we live in this short and most
recent Geological Era.
Page 33
What is Cenozoic?
Page 34
Canada’s oldest landform, the Canadian Shield, was formed in this ancient Geological Era.
Page 35
What is Precambrian?
Page 36
The era when the Pangaea formed.
Page 37
What is Paleozoic?
Page 38
4.6 billion years
Page 39
What is the age of the Earth?
Page 40
The period represents 87% of Earth’s geological time, and during this period,
Earth’s atmosphere began to convert from carbon dioxide and methane to
oxygen
Page 41
What is the Precambrian?
Page 42
The centre made mostly of iron.
Page 43
What is the Inner Core?
Page 44
The layer we live on.
Page 45
What is the Crust?
Page 46
Magma is found here.
Page 47
What is the Mantle?
Page 48
Between 6 and 100 kilometres thick
Page 49
What is the Crust?
Page 51
What is the number of layers
in the Earth?
