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 ...
Conceiving that such a compilation might help to supply my own deficiencies, I had, in the year 1805, completed a classed catalogue of words on a small scale, but on the same principle, and nearly in the same form, as the Thesaurus now published. [4] Roget's Thesaurus is composed of six primary classes. [5]
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]
Synonym list in cuneiform on a clay tablet, Neo-Assyrian period [1] A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. [2] For example, in the English language, the words begin, start, commence, and initiate are all synonyms of one another: they are ...
A bergschrund is distinct from a randkluft, which is a crevasse with one side formed by rock. The randkluft arises in part from the melting of the ice due to the presence of the warmer rock face. [2] However, a randkluft is sometimes called a bergschrund. [3] The French word rimaye encompasses both randklufts
A randkluft (from the German for marginal cleft/crevasse) or rimaye (from the same French IPA:) is the headwall gap between a glacier or snowfield and the adjacent rock face at the back of the cirque [1] or, more loosely, between the rock face and the side of the glacier. In French, the word rimaye covers both notions of randkluft and bergschrund.
These crevasse channels are essentially miniature distributary systems and can have many of the features that larger fluvial bodies possess, like levees. [4] A crevasse-splay sequence typically begins with an erosive base, followed by the deposition of coarse bed load sediment and transitioning to finer suspended sediment as energy decreases ...
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.
