Quizplus · Accepted Answer

Accumulated rock-fall debris along the margin of a glacier is called a lateral moraine. A medial moraine is formed when two glaciers come together and their respective lateral moraines merge. Eskers are long, sinuous ridges of sand and gravel that were deposited by streams that flowed under and probably within glaciers. Kames are small hills or mounds of sediment that were deposited by meltwater streams that flowed on, within, or beneath glaciers.
