The processes by which
granite breaks down to
sediment.
What are
Erosion and Weathering?
The type of rock that
INTENSE PRESSURE
creates.
What is Metamorphic?
Slate become this
when it is heated.
What is Magma?
Limestone, chalk and
sandstone are this type of
rock that form from
sediments.
What is Sedimentary rock?
These are rocks that
solidified directly from molten
silicates (i.e., magma).
Examples are granite, basalt,
pumice and flint.
What is Igneous rock?
This is Canada’s oldest landform.
What is
the Canadian Shield?
The Rocky Mountains are
found in this landform.
What is
the Western Cordillera?
This landform is Canada’s
oldest Highland landform.
What is
the Appalachian Highlands?
This western landform has
deep fiords.
What is
the Western Cordillera?
This landform has the
nickname
“Canada’s Heartland.”
What is
the St. Lawrence
and
Great Lakes Lowlands?
The temperature is about
4,800OC. The pressure is over
3.6 million times the pressure
at the Earth’s surface.
Gravity is ZERO.
What is
the centre of the Earth?
Wegener proposed this
theory to explain the shape of
the Earth’s land masses.
What is
Continental Drift?
One large land mass
What is Pangaea?
The movement of the
Earth’s plates by
convection currents in the
semi-molten layer of the
Mantle
What is
Plate Tectonics?
Constantly changing due to
forces such as erosion and
deposition, this outermost
layer of the Earth is between
6 and 100 km thick.
What is the Crust?
Called the Age of Mammals,
we live in this short and most
recent Geological Era.
What is Cenozoic?
Canada’s oldest landform, the
Canadian Shield, was formed
in this ancient Geological Era.
What is Precambrian?
The era when
the Pangaea formed.
What is Paleozoic?
4.6 billion years
What is the age of the Earth?
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
What is the Precambrian?
The centre
made mostly of iron.
What is
the Inner Core?
The layer we live on.
What is the Crust?
Magma is found here.
What is the Mantle?
Between 6 and 100 kilometres
thick
What is the Crust?
Four
What is
the number of layers
in the Earth?
