Detailed explanation-1: -The most common depositional landform created by glaciers is a moraine.

Detailed explanation-2: -Kettles. As a glacier recedes, sediment is washed out from the glacier and deposited in a flat area below, forming an outwash plain. Depressions, known as kettles, often pockmark these outwash plains and other areas with glacial deposits.

Detailed explanation-3: -The major deposition landforms are beaches, spits and bars. Deposition occurs when wave velocities slow, or when ocean currents slow due to encountering frictional forces such as the sea bed, other counter currents and vegetation.

Detailed explanation-4: -Glacial deposition is the settling of sediments left behind by a moving glacier. As glaciers move over the land, they pick up sediments and rocks. The mixture of unsorted sediment deposits carried by the glacier is called glacial till. Piles of till deposited along the edges of past glaciers are called moraines.

Detailed explanation-5: -A roche moutonée is a glacial landscape feature produced as an advancing glacier slides over a hill of surface bedrock. As the glacier advances up the side of the hill, the surface bedrock is abraded and smoothed by rock fragments carried within the base of the glacial ice, creating a more gentle hillslope.
