What is the difference between Bergschrund and crevasse?
A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Bergschrunds are cracks that appear between the moving ice of a glacier and the non-moving, or stagnant, ice of a mountain or cliff.
How Bergschrund are formed?
A bergschrund (from the German for mountain cleft) or rimaye (from French; pronounced [ʁimaj]) is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. It is caused by the rotational movement of the glacier.
What is the difference between crevice and crevasse?
Crevasse refers to a deep hole or fissure in a glacier or earth. One way to remember the distinction between crevice and crevasse is that i (as found in crevice, the smaller hole) is a thinner letter than a (as found in crevasse, the larger hole).
How are crevasses created?
A crevasse is a crack in the surface of a glacier caused by extensive stress within the ice. For example, extensive stress can be caused by stretching if the glacier is speeding up as it flows down the valley. Crevasses can also be caused by the ice flowing over bumps or steps in the bedrock.
