Transverse crevasses, Chugach State Park, Alaska. 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. The resulting intensity of the shear ...
A common form of crevice failure occurs due to stress corrosion cracking, where a crack or cracks develop from the base of the crevice where the stress concentration is greatest. This was the root cause of the fall of the Silver Bridge over the Ohio River , in 1967 in West Virginia , where a single critical crack only about 3 mm long suddenly ...
A crevasse splay is a sedimentary fluvial deposit which forms when a stream breaks its natural or artificial levees and deposits sediment on a floodplain. A breach that forms a crevasse splay deposits sediments in similar pattern to an alluvial fan deposit. Once the levee has been breached the water flows out of its channel.
Scientists are torn about why a massive crack in the earth suddenly appeared outside Nairobi, Kenya.
A crevasse may be as deep as 45 m (148 ft) and as wide as 20 m (66 ft). [11] A crevasse may be covered, but not necessarily filled, by a snow bridge made of the previous years' accumulation and snow drifts. The result is that crevasses are rendered invisible, and extremely dangerous to anyone attempting to traverse a glacier. [12]
A bergschrund (from the German for mountain cleft; sometimes abbreviated in English to "schrund") is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. [1] It is often a serious obstacle for mountaineers. Bergschrunds extend to the bedrock, and can have a depth of well over 100 metres (330 ft).
