Question

Quizplus · Accepted Answer

Basal slip is the movement of a glacier over its bed due to the melting and refreezing of the ice at the base of the glacier, creating a layer of water that allows the glacier to slide. Crevassal slip is not a term commonly used to describe glacier movement, frost heaving is a process where the expansion of frozen water in soil causes lifting, and morainal sliding is not a recognized term in glaciology.
