How do glacial crevasses form
WebCrevasses and Crevices. A "crevasse" is a large deep crack in the surface of a glacier, caused by the ice flowing over uneven terrain. • When a glacier moves around a sharp bend in a valley, the ice on the inside edge moves … WebWhen a glacier moves through irregular terrain, cracks called crevasses develop in the fracture zone. Crevasses form due to differences in glacier velocity. If two rigid sections of a glacier move at different speeds and directions, shear forces cause them to break apart, opening a crevasse.
