Erosional feature produced by alpine valley glaciers is called Cirque. These are formed at the head of glacier and are formed by glacier pushing back into the mountain top. A cirque is characterized by bowl shaped depression at the head of the glacial valley. When a mountain top is eroded and multiple cirques are present on its sides, a pyramidal peak is obtained, which is known as Horn. Some of the other erosional features created...
Erosional feature produced by alpine valley glaciers is called Cirque. These are formed at the head of glacier and are formed by glacier pushing back into the mountain top. A cirque is characterized by bowl shaped depression at the head of the glacial valley. When a mountain top is eroded and multiple cirques are present on its sides, a pyramidal peak is obtained, which is known as Horn. Some of the other erosional features created by alpine valley glaciers are hanging valley, arete, tarn, etc.
For comparison, moraines are formed by deposition of material carried by glaciers. Eskers are formed by streams flowing within a glacier and are composed of sand and gravel. Drumlins are formed by movement of glaciers over land and are composed of rock, sand and gravel.
Hope this helps.
