Glaciated landscapes feature distinctive landforms created by glacial erosion and deposition. Some examples include corries, which are deep hollows with steep back walls that often form tarns after glacial retreat. Hanging valleys are smaller tributary valleys left at higher elevations after a main valley was deepened by glaciation. When three or more corries cut into a mountain, they can form a pyramidal peak or horn-like shape separated by narrow ridges called arêtes. U-shaped valleys have wide, flat floors and truncated spurs compared to the narrow, steep sides and winding course of pre-glacial V-shaped valleys.

1. Glaciated Landscapes Corrie Deep rounded hollows with a steep back wall. After the ice has melted a lake will be formed behind the rock lip , the lake is called a tarn Examples Mt Snowdon – N Wales Helvellyn – Red Tarn – Lake District

2. Corrie - Helvelyn - Red Tarn (Lake D) Steep back wall Tarn Rock lip

6. Mt Everest - Pyramidal Peak Corries either side When 3 or more corries cut into a mountain a pyramidal peak or horn develops. Arêtes separate the corries. Perhaps the most famous one is ?

7. The Matterhorn - Switzerland

8. U Shaped Valley's V shaped river valley – narrow floor, steep sided and winding U shaped, straight, wide flat floor with truncated spurs

10. Arete - Striding Edge (Lake D) When 2 or more corries are side by side / back to back. They erode towards each other so that the land between them gets narrower and narrower until a knife edge ridge forms, called an Arête . Back wall of corrie either side Arete

12. Ribbon Lake - Thirlmere (L District) A lake in the bottom of a glacial trough formed by lots of plucking or deposition of moraine. There are many examples in the lake District such as Windermere, Buttermere or Coniston water. Long narrow lake, water may be dammed up behind terminal moraine Bottom of lake could be softer rock Can form when tributary glacier joins to add to the amount of erosion
