Glaciers in arctic regions that are frozen to their beds move via internal deformation.

Question

Quizplus · Accepted Answer

Glaciers in arctic regions are typically cold-based, which means they are frozen to their beds. As a result, they move via internal deformation, in which the ice deforms and flows under pressure from the weight of the ice above. This is in contrast to temperate glaciers, which have a layer of meltwater at their base and can slide along their beds.
