Plucking

Explanation:

Glacial erosion, the picking up and movement of earth beneath a glacier, is also known as plucking. Plucking occurs in "valley glaciers." First, the bottom part of the glacier melts due to the friction generated by the movement of the glacier. This allows ice to infiltrate cracks in the bedrock. As this ice freezes and thaws, it causes further cracks, gradually loosening the rocks. The rocks become trapped in the glacier, leading to erosion.
