Question

Quizplus · Accepted Answer

Glaciers can indeed surge and advance at a rapid pace of up to 12 inches per day. This occurs when there is a sudden increase in the rate of ice flow, often caused by a build-up of water underneath the glacier. Surging glaciers are relatively rare, but they can have significant impacts on surrounding ecosystems, infrastructure, and communities.
