Question

Quizplus · Accepted Answer

The gray feature between the two heavy black lines in the toe of the glacier is a moraine, which is a ridge or mound of glacial till (debris) deposited by a glacier. Eskers are narrow ridges of sediment deposited by subglacial streams, and aretes are sharp ridges formed by two glaciers eroding parallel U-shaped valleys. The zone of accumulation refers to the upper part of a glacier where more snow accumulates than melts.
