Question

Quizplus · Accepted Answer

Arêtes are sharp ridges that form when glaciers erode parallel valleys by carving away the rock and ice from either side of the ridge, leaving a sharp crest in between. Eskers are long, winding ridges of sediment deposited by meltwater streams flowing on top of glaciers, while bergschrunds are crevasses that form at the top of a glacier where the ice is moving at a different pace than the ice below. Drumlins are elongated hills that are streamlined in the direction of ice flow and are formed by the deposition of sediment by retreating glaciers.
