Plucking and abrasion are key processes in glacier erosion. Plucking picks up rocks and sediments, while abrasion scours and wears away rock surfaces.
Explanation:
Plucking involves picking up rocks and sediments by a glacier. These materials freeze to the glacier's bottom and are then carried away by the moving ice. On the other hand, abrasion is a process where glaciers scrape underlying rock by acting like sandpaper, wearing away at the rock surfaces and leaving scratch marks that indicate the glacier's movement direction.
