Origin and development of erosional landforms: corries, arêtes, glacial troughs, hanging valleys, truncated spurs, roches moutonnées
Moving ice carves distinctive landforms into upland rock. Corries, glacial troughs, and arêtes are all products of this erosion by glaciers.
Real World
Snowdon's north-facing corrie (Cwm Llydaw) shows classic armchair-shaped erosion, with a rock lip and tarn, used by geographers as a textbook example of rotational sliding and freeze-thaw weathering working together.
Exam Focus
For landform questions, always state the process, explain the mechanism, and name the resulting feature — missing one step typically loses a mark.
