What 4 forces create Canada’s typography
- The building-up of forces of mountain building
- The wearing down forces of weathering or exposure to the atmosphere
- The wearing down forces of a Erosion
- The building up forces of deposition where eroded materials add new shapes
Continental Drift
The theory that earths continental plates are moving.
