Quizplus · Accepted Answer

A cirque is a bowl-shaped depression at the head of a glacier, often containing a lake, and is typically the first feature carved by a mountain glacier. An arete is a sharp, thin ridge that is formed when two glaciers erode parallel U-shaped valleys. A horn is a pyramid-shaped peak that is created when multiple glaciers erode the sides of a mountain. A moraine is a deposit of unconsolidated rock and soil that is transported by a glacier. An erratic is a large boulder that is transported and deposited by a glacier, often in a location far from its source rock.
