Glaciers erode land through Plucking and Abrasion.
Answer: Option C
Step-by-step explanation:
Glaciers are mass form of ice found in the high altitudes. During summer the glaciers melt down and rich source of pure water is obtained. Glaciers erode through two main processes and they are plucking and abrasion.
Sometimes water freezes around the broken or cut down rocks and when in summer when it melts it forces the rock out and this is called plucking. When water enters into the crack and then at night when the water freezes within it breaks the rock.
