Question

piece of rocks,sand and silt debris deposited by glaciers.......​

Answer 1

Answer:

Moraines. As a glacier moves along a valley, it picks up rock debris from the valley walls and floor, transporting it in, on, or under the ice. As this material reaches the lower parts of the glacier where ablation is dominant, it is concentrated along the glacier margins as more and more debris melts out of the ice.
