Identify the glacial landform feature

• Fissures

Describe the process of plucking

• Rocks become frozen into the bottom and sides of a glacier, and as the glacier moves downhill it takes the rocks frozen into the glacier with it

• Deep grooves in surface rocks, made by the sharp edges of stones carried at the base of a glacier

• A body of land-based ice that moves under its own weight due to gravity

• The process of rocks breaking up because of repeated freezing and thawing of water within cracks
