Plate Tectonics & Natural Disasters
What is the name of the supercontinent that existed millions of years ago before the plates drifted apart?
Pangea
What is the innermost layer of the Earth?
Inner core
A large, moving mass of ice that forms from compacted snow over time.
Glacier
This type of rock forms when small pieces of rock are compressed together.
Sedimentary rock
What is the largest landform region in Canada?
Name two examples of natural disasters caused by tectonic activity.
Earthquakes/volcanoes/tsunamis
Which layer of the Earth is solid and forms the Earth's outer shell?
Crust
What type of glacier covers large areas of land, like Greenland or Antarctica?
Continental Glacier
Which rock type forms from cooling magma or lava?
Igneous rock
Which landform region contains Canada’s tallest mountains?
Western Cordillera
What type of plate boundary occurs when two plates move away from each other?
Divergent boundary
What layer of the Earth is made of molten rock (magma)?
Mantle
What glacial process involves ice picking up rocks as it moves?
Plucking
What rock type is formed by heat and pressure changing existing rock?
Metamorphic rock
What vegetation region includes flat prairie landscapes with little trees and rich farming soil?
Grasslands
What type of plate boundary forms when two plates move toward each other, causing mountains or trenches?
What process in the mantle causes plate movement?
Convection currents
These glacial features have a gentle hill on one side and a steep slope on the other.
Drumlins
What natural processes break down rocks into sediment?
Weathering and erosion
This boundary is the theoretical northernmost point where trees can grow in Canada
Tree line
What has China developed as a possible solution to urban flooding?
Sponge cities
The Earth's outer core is liquid and made up mostly of what elements?
Iron and Nickel
Due to their weight, most glaciers move along this gravitational slope.
Topographic gradients
This process is where transported sediments, soil, and rock particles settle and accumulate in a new location.
Deposition
Why are the Great Lakes Lowlands a popular place for Canadian manufacturing and shipping?
Proximity to the US border, large population centres
