Glacial Erosion Describe and explain the location and variety of features of glacial erosion' (20 marks) Glacial erosion has a massive impact on the landscape and can take thousands of metres off the landscape. There are a number of ways that the landscape can be eroded that form a number of varied features. These features are formed in different areas depending on the feature, as features can only be formed in certain areas. The first landform that I?m going to discuss is a corrie. These are an armchair-shaped basin with a steep back wall and a rock basin. They are formed by a number of processes, nivation is considered to be one of the main initiators of corries. This happens when snow accumulates in hollows and freeze-thaw action beneath the snow causes the underlying rocks to disintegrate, any debris is carried out by summer meltwater streams. The snow patch would grow and the layers would become compressed to form ice. After this plucking is responsible for the steepening of the back wall and rotational movement enables abrasion for the deepening of the corrie basin. Corries locate up the side of mountains and have a very clear dominant orientation.
