Glaciers move very slowly from uplands to the lowlands. The transport of glaciers has a deep impact on the landscape. The moving glaciers drift the rocks and the debris along with them. This transportation of the debris is known as glacial transportation. The whole glacier work is carried out in the following forms.
- Weathering caused due to freeze and thaw: As freeze-thaw weathering occurs along the edge of the glacier pieces of rock, which break off larger rocks, fall onto the glacier, and are transported.
- Plucking of the Rocks by Ice Block: Rocks plucked from the bottom and sides of the glacier are moved downhill with the ice.
- Pushing the in-front-rocks: Bulldozing is when rocks and debris, found in front of the glacier, are pushed downhill by the sheer force of the moving ice.
- Twisting Movement of the Glaciers: Rotational slip is the circular movement of the ice in the corrie.
The material and debris shifted by the glaciers from the upland to the lowlands are known as Moraine.
- Lateral moraine: 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.
- Medial moraine: Material deposited in the middle of the glacier. This is caused by the lateral moraines of two glaciers when they meet.
- Terminal moraine: Material deposited at the end of the glacier.
