Glacial processes and landforms
Glaciers shape the land through processes of weathering, erosion, transportation and deposition, creating distinct landforms.
Case Study: Snowdonia, Wales
Cwm Clyd and Cwm Idwal are excellent examples of corries in Snowdonia. They have distinctive glacial features such as:
- steep back wall, created byfreeze-thaw weathering and plucking
- steep sided and narrow ridges called arêtes
- a corrie lake
