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 - National Geographic Society 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 | 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
What is a Crevasse? - LiveAbout A crevasse is a crack, crevice, or fracture in a glacier or moving mass of ice that forms from the movement and stress of the glacier, especially as it moves downhill Stress in the ice caused by the glacier’s movement causes crevasses to open and close
Glacier Power: What are Crevasses? | NASA Earthdata 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
