Lesson Details
Key learning points
- Glaciers create wide U-shaped valleys through the process of erosion.
- Truncated spurs are formed when a glacier cuts off interlocking spurs.
- Corries are bowl-shaped hollows found on the side of hills and mountains.
- Aretes are sharp peaks formed by two glaciers wearing down either side of a mountain.
Common misconception
Truncated spurs are created soley by glaciers.
Truncated spurs started as interlocking spurs which are a fluvial feature formed by rivers. Glaciers then modify this landform through erosion.
Keywords
Corrie - a steep-sided hollow at the head of a valley or on a mountainside
Truncated spur - a ridge that ends in a steep cliff face where an interlocking spur formed by rivers has been cut off by a glacier
Arete - a narrow ridge of rock between two valleys
U-shaped valley - a valley with steep, straight sides and a flat bottom, formed by the movement and scouring action of a glacier
