Plucking – A type of erosion where melted water in a glacier freezes onto rocks and as the ice moves forward it plucks out large pieces along the rock joints

To remember the meaning of the term Plucking, use the following mnemonic:

Plucking out an eyebrow hair is just the same as plucking in geography. It will come out eventually if it's pulled hard enough.

Plucking happens when rocks and stones that have been frozen to the base or sides of the glacier are plucked from the ground or rock face as the glacier moves. The rock that is plucked has often been weakened by long periods of freeze-thaw weathering and abrasion.
