difference between abrasion and plucking
Plucking and Abrasion Defined. Plucking involves movement of large chunks of rock; abrasion is the sandpaper-like effect of rocky debris scouring land. Both are mainly attributed to the movement of glaciers, which the U.S. National Park Service refers to as nature's landscape architects..
Abrasion and plucking. Plucking occurs when rocks and stones become frozen to the base or sides of the glacier and are plucked from the ground or rock face as the glacier moves. It leaves behind a jagged landscape. Abrasion occurs when rocks and stones become embedded in the base and sides of the glacier. These are then rubbed against the bedrock (at the bottom of the glacier) and rock faces (at the sides of the glacier) as the glacier moves. This causes the wearing away of the landscape as the glacier behaves like sandpaper.
