- Glacial Erosion
- Abrasion
- The sandpapering effect of glacial ice as it grinds over and scours a landscape
- Plucking
- 1 This occurs when the refreezing of meltwater freezes part of the underlying bedrock to the base of the glacier
- 2) Any loosened rock fragments are then "plucked" away when the glacier moves forward
- Abrasion
- Glacial Transportation and deposition
- 1) Glaciers act like giant conveyer belts - transporting material on, in and below the ice
- 2) This material, called moraine is deposited when the glacial ice starts to melt
- Roche Moutonnee
- This is a rock formation created by the passing of a glacier
- They have a smooth side and a jagged side
- The process of abrasion eroded the smooth side
