8

What geological processes formed the Canadian Shield?

- Used to be an area of mountains and volcanoes
- Erosion have created present topography

9

What geological processes formed the Great Lakes - St. Lawrence Lowlands?

Used to be under glaciers that retreated

10

What geological processes formed the Western Cordillera?

- Rocky + Columbia mountains formed by faulting and folding
- Interior Plateaus were formed by volcanic activity
- Coast Mountains = collision zone

11

What geological processes formed the Interior Plains?

- Seas covered the Interior Plains was deposited with sediments
- Was compressed into rock

12

What geological processes formed the Innuitians?

- Erosion has not worn down mountains yet
- Shaped when North American plate moved north

13

What geological processes formed the Arctic Lowlands?

- Glacier sunk Canadian Shield, then retreated
- This formed lowlands - still rising

14

What geological processes formed the Appalachians?

- North American plate collided with African, forming mountains
