  • Crevasses
definition
  • A crack in an ice sheet or glacier (compare to crevice, which is in rock). Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, etc.; these walls sometimes expose layers that represent the glacier's stratigraphy.

Abstract from DBPedia
    A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. 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 stress causes a breakage along the faces.
