name the important horn on glacier horn in the switch
Answers
Answer:
The Matterhorn, part of the Alps in Switzerland, is a glacial horn. A horn is formed as three or more glaciers meet, forcing the land between them up into a peak. In fact, another name for a horn is a pyramidal peak.
A horn results when glaciers erode three or more arêtes, usually forming a sharp-edged peak. Cirques are concave, circular basins carved by the base of a glacier as it erodes the landscape. The Matterhorn in Switzerland is a horn carved away by glacial erosion.
Answer:
A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
Explanation:
FORMATION
Glaciers, typically forming in drainages on the sides of a mountain, develop bowl-shaped basins called cirques (sometimes called ‘corries’ - from Scottish Gaelic coire [kʰəɾə] (a bowl) - or cwms). Cirque glaciers have rotational sliding that abrades the floor of the basin more than walls and that causes the bowl shape to form. As cirques are formed by glaciation in an alpine environment, the headwall and ridges between parallel glaciers called arêtes become more steep and defined. This occurs due to freeze/thaw and mass wasting beneath the ice surface. It is widely held[by whom?] that a common cause for headwall steepening and extension headward is the crevasses known as bergschrund that occur between the moving ice and the headwall
