Question

Quizplus · Accepted Answer

The movement of a glacier is fastest at its surface because it is exposed to the most sunlight, wind, and other environmental factors that can contribute to meltwater formation, which in turn lubricates the ice and allows it to slide more easily over the underlying rock or soil. Additionally, the top layer of ice is subjected to less friction than the underlying layers, which can slow down its movement.
