Glacial Geomorphology
Glaciers erode rock by abrasion and plucking. During this process, Glaciers produce many erosional features such as: moraines, erratics, drumlins, valleys, cirques, aretes, and hornes. A glacier plucks rock by softening and lifting the rock. Abrasion is caused when glaciers flow over rock and smooth or polish it. rate of glacier erosion is caused by velocity of glacier, thickness, shape, permeability, and water pressure. Glacier carries material and deposits it in the form of glacial till. Glaciers pluck, carry and deposit rocks suchs as glacial till and erratics of all sizes. A glacial moraine is a deposit of a glacier left after it has retreated near the location of the zone of ablation or foot of glacier. This is the location of a terminal moraine. Lateral moraines are on the edge of the glacier where the rate of flow is the lowest. Medial moraines are located in the center of the glacier where the rate of flow is the highest. Other erosion features, such as cirques, aretes, and horns, are created as a glacier erodes valleys and mountains. This also forms glacial valleys. A Drumlin is another type of erosional feature. Drumlins are carved on the earth surface by glaciers. They are teardrop shaped and tend to point towards the direction of flow of the glacier. Drumlins have height and width. Drumlins are found in groups called drumlin fields.
Water melts from a glacier at the zone of ablation. Often the glacier recedes at the zone of ablation due to this melt and some sublimation.
