Question

Quizplus · Accepted Answer

Crevasses are defined as open fissures or cracks that form in the brittle surface ice of glaciers due to the movement and stress of the ice. Cirques are bowl-shaped depressions at the head of a glacier, while joints are cracks in rock formations. Arêtes are narrow ridges that separate two glacier valleys, and thalwegs are the deepest parts of a river or stream channel.
