Question

Quizplus · Accepted Answer

Basal slip is a process where the glacier moves over its bed by sliding at the ice-bed interface, often facilitated by meltwater acting as a lubricant. This is one of the primary mechanisms through which glaciers can move. Frost heaving and morainal sliding are not recognized mechanisms for glacier movement over its bed, and crevassal slip refers to the movement within the glacier ice itself, not its movement over the bed.
