Processes of glacial transportation
Glaciers move very slowly. As they move, they transport material from one place to another:
- As When water in rocks freezes and expands, breaking the rock apart. occurs along the edge of the glacier pieces of rock, which break off larger rocks, fall onto the glacier and are transported.
- Rocks A type of glacial erosion that occurs when ice freezes onto the landscape, ripping out rocks when it moves. from the bottom and sides of the glacier are moved downhill with the ice.
- When rocks and debris found at the front of the glacier are pushed downhill with the ice. is when rocks and debris, found in front of the glacier, are pushed downhill by the sheer force of the moving ice.
- Movement of the ice out of the corrie in a circular motion. is the circular movement of the ice in the corrie.
Any material carried or moved by a glacier is called moraine. There are three different types of moraine:
- Moraine found along the edge of the glacier. - material deposited along both sides of the glacier. This moraine is usually made up of weathered material that has fallen from the valley sides above the glacier.
- A landform resulting from glacial material (till) deposited between two glaciers. - material deposited in the middle of the glacier. This is caused by the lateral moraines of two glaciers when they meet.
- Moraine (debris) left at the furthest point the glacier reached. - material deposited at the end of the glacier.
