- 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. Below that, a glacier is less brittle and can slide over uneven surfaces without cracking.

What causes a crevasse to form?
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, 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 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."
A crevasse is a fissure or crack in a glacier that forms from movement-induced stress. Crevasses range to 65 feet (20 meters) wide, 148 feet (45 meters) deep, and hundreds of yards long. There are several different types. A transverse crevasse occurs where the valley becomes steeper.
Mar 17, 2017 · 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.
May 8, 2018 · 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.
