How does the process of plucking cause erosion?
1 answer
Plucking is when parts and pieces of the earth (rocks and soil) are picked up by a moving glacier. As the glacier freezes the rocks and soil are frozen to the bottom of the glacier. As the glacier melts and moves the rocks are dragged along the earth digging up more earth and bits as they go. Thus they are eroding the earth as the glacier moves : )
