Question

Quizplus · Accepted Answer

Crevasses generally form as a result of tensional forces, which result in cracking and fracturing of the ice. These forces can be caused by the movement of glaciers, changes in the topography of the land underneath the ice, or changes in temperature or pressure. Regelation and ablation are processes that may contribute to the formation of crevasses, but they are not the primary causes. Deposition is not typically associated with crevasse formation.
