i) Hanging valley.
- There exist river valleys, both the main and tributary valley.
- A glacier occupies former river valley.
- Both the main and tributary valley are occupied by the glacier.
- There will be more erosion on the main valley compared to tributary valley.
- The main valley is therefore deepened and widened faster than tributary valley.
- The suspended tributary valley forms a hanging valley.
ii) Arête.
- Two adjacent cracks or hollows exist on a mountain side.
- The two hollows or cracks are filled with ice.
- The ice erodes the sides through plucking and deepens the hollow through abrasion.
