Question

Quizplus · Accepted Answer

The term roche moutonnée describes an asymmetrical hill of exposed bedrock that has been shaped by glacial erosion. The gentle, upstream side of the hill has been smoothed by abrasion, while the downstream side has been plucked and is typically rough and jagged. Eskers are ridges of sediment deposited by meltwater streams within or beneath glaciers, drumlins are smooth, elongated hills made of glacial till, and bergschrunds are crevasses that form where moving ice separates from stagnant ice.
