Crevasse - Wikipedia
A crevasse is a deep crack that forms in a glacier or ice sheet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement.
Crevasse Definition & Meaning - Merriam-Webster
Crevasse refers to a deep hole or fissure in a glacier or in the earth. In most instances, the word appears with enough context that the depth of the opening is easy enough to figure out, as in "a climber who fell 30 feet into a crevasse."
'Crevice' and 'Crevasse': A Gap in Meaning | Merriam-Webster
Crevice and crevasse are very similar words: they both derive from the Old French crever, a verb meaning "to break or burst," and both refer to an opening of some kind. In fact, you can say that the only notable distinction between the two is the size of the openings they denote.

Crevasse | Glacial, Ice Shelf, Fracture | Britannica
Crevasse, fissure or crack in a glacier resulting from stress produced by movement. Crevasses range up to 20 m (65 feet) wide, 45 m (148 feet) deep, and several hundred metres long. Most are named according to their positions with respect to the long axis of the glacier.
crevasse - National Geographic Society
2023年10月19日 · A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle. Encyclopedic entry.
Crevasse - Encyclopedia.com
2018年5月8日 · crevasse 1. A deep fissure in the surface of a glacier, caused when tensile stress overcomes the shear strength of ice in the brittle upper few metres. Appropriate tensile stresses are typically developed when a glacier moves over a convex slope.

Glacier crevasses: Observations, models, and mass balance …
2016年1月12日 · We review the findings of approximately 60 years of in situ and remote sensing studies of glacier crevasses, as well as the three broad classes of numerical models now employed to simulate crevasse fracture.
What Are The Differences Between A Crevasse And A Crevice
2018年3月16日 · A crevasse occurs in wet places mainly covered with snow and is therefore not easily visible, but a crevice will occur on dry land and can be easily identified. Thus, crevasse is very dangerous to a human being or to animals such as the polar bears which can fall into it and die due to hypothermia.
