Answer

Plucking

Plucking is a process in glacial erosion where glaciers remove or dislodge rocks from the bedrock as they move. This occurs when the ice freezes around the rocks and then pulls them away as the glacier advances, contributing to the landscape's reshaping.

Abrasion

Abrasion refers to the wear and tear caused by the grinding action of particles carried by the glacier. As glaciers move, they scrape the underlying rock surface, leading to smoothened areas and striations on the rock, ultimately altering the landscape.
