Question

Quizplus · Accepted Answer

Striations, roches moutonnées, and drumlins are landforms that are created by glacial ice movement. Striations are scratches on bedrock caused by rocks being dragged along by the glacier; roches moutonnées are bedrock outcrops that have been eroded and smoothed by glacial ice; and drumlins are elongated hills that have a steep side facing the direction of ice movement and a gentle slope on the other side. By examining these features, geoscientists can determine the direction in which the glacier was moving.
