Pyramidal Peaks, Horns and Aretes
When a cluster of cirques from around the slopes of a high peak then pyrimidal peaks and horns are able to form.
Along the edge separating two cirques, razor sharp aretes develop - matterhorn, switzerland
Glacial Deposits
-
Eratics
Erratics are large boulders and rocks that are a different type of rock compared to the dominant geology of the area where they stand. They were deposited by previous glaciers.
-
Glacial erosion
Glaciers have massive capacity to erode landscapes, due to their vast
size, weight and constant movement.
-
U shaped valleys
As glaciers move down valley they continue to reshape it. Valley glaciers are much bigger than cirque glaciers and carry much greater mass of ice. This enables them to erode through abrasion and plucking at a much faster rate. The resulting landform after glaciation is a deep and wide U-shaped valley, with truncated spurs.
