Glaciation

|
Glacial Processes:
1. Frost Shattering
3. Abrasion
|
2. Plucking
Just like with coasts and rivers, glaciers also have the ability to erode, transport and deposit material.
This creates glacial landforms/ features. Landforms of erosion include: Cirques (corries) Arêtes Pyramidal Peaks U-shaped Valley Hanging Valley Truncated Spur Landforms of Deposition include: Moraines Drumlins An Esker is a landform of deposition created by the glacier's meltwater stream. |
