Erosional and depositional features of glaciers

depositional features..
As glaciers flow over many years, all sorts of debris falls onto the glacier through mechanical weathering of the valley walls. Glaciers are solid ice, so unlike water, they can carry pieces of rock of any size. Glaciers move boulders as large as a house as easily as the smallest particles of sand and silt. These pieces of rock are carried by the glacier for many kilometers and are only deposited as the ice melts. When you think of a glacier, you may think of white ice and snow, but actually glaciers have lots of rocky bits all over them. Each of these different deposits has its own name based on where it forms, but as a group they are called moraines. A long pile of rocky material at the edge of a glacier is called a lateral moraine and one in the middle of the glacier is called a medial moraine. Lateral moraines form at the edges of the glacier as material drops onto the glacier from erosion of the valley walls. Medial moraines form where two glaciers join together. In this case, the lateral moraines from the edges of each glacier meet in the middle to form the medial moraine
