With glaciers on three or more sides of a mountaintop, steep peak called a horn is formed.
Explanation:
The glaciers have very big erosive power. With the enormous wight they have, the pressure and force they create, the glaciers manage to create lot of different erosive features on the landscape. The erosion by the glaciers works in a simple manner; the glacier with its wight creates lot of force and pressure on the rocks that it touches, the rocks break apart, and a feature is formed, usually by the shape of the glacier itself.
The horns are one of the glacial erosive features. This feature is formed where at a mountain top there are three glaciers on different sides. All three glaciers erode the sides on the mountain, through which they sharply break apart the sides, creating a very steep, pyramidal, mountain top.
Other glacial features are:
- arete
- moraine
- cirque
- valley step
- U-shaped valley
- Fjord
