Question

Quizplus · Accepted Answer

Basal slip is facilitated by regelation, which is the process of melting and refreezing of ice due to pressure changes. The presence of melt water also reduces friction between the ice and the bed, allowing for easier basal slip. Saturated sediments can also act as a lubricant, further facilitating basal slip. Therefore, all of these factors together facilitate basal slip.
