What is Metamorphic?
6
Slate become this when it is heated.
7
What is Magma?
8
Limestone, chalk and sandstone are this type of
rock that form from sediments.
9
What is Sedimentary rock?
10
These are rocks that solidified directly from
molten silicates (i.e., magma). Examples are
granite, basalt, pumice and flint.

What is the centre of the Earth?
24
Wegener proposed this theory to explain the shape
of the Earths land masses.

What is Pangaea?
28
The movement of the Earths plates by convection
currents in the semi-molten layer of the Mantle
29
What is Plate Tectonics?
30
Constantly changing due to forces such as erosion
and deposition, this outermost layer of the Earth
is between 6 and 100 km thick.
31
What is the Crust?
32
Called the Age of Mammals, we live in this short
and most recent Geological Era.

What is Cenozoic?
34
Canadas oldest landform, the Canadian Shield,
was formed in this ancient Geological Era.

What is Precambrian?
36
The era when the Pangaea formed.
37
What is Paleozoic?
38
4.6 billion years

The period represents 87 of Earths geological
time, and during this period, Earths atmosphere
began to convert from carbon dioxide and methane
to oxygen
