Question

Quizplus · Accepted Answer

Basal slip can cause a glacier to move relatively rapidly through a process called surging. During a surge, the glacier may move several meters per day, much faster than typical glacial movement. This is due to the sudden release of stored forward potential energy that has been built up over time as the glacier slowly deforms and thickens by internal deformation.
