2 of 9
Describe the formation of an arete.
An arete is a knife edged ridge formed at the back of 1 Corrie or separating 2 Corries/Glaciers.
3 of 9
Describe the formation of pyramidal peaks.
Pryamidal peaks are formed when 3 or more glaciers/corries cut backwards into the same mountain.
4 of 9
Describe a valley before glaciation.
Rounded watershed, V-shaped valley, Interlocking spurs, Tributarys.
5 of 9
Describe a valley after glaciation.
Truncated spurs, Hanging valley, U-shaped valley, Ribbon lakes, Glacial trough, jagged watershed, miss fill stream.
6 of 9
Describe a truncated spur/ formation of a truncated spur.
When a glacier pushes straight through a valley and removes the ends of interlocking spurs.
7 of 9
Describe a Glacial trough/ formation of a glacial trough.
A glacier changes the shape of a valley from V-shaped to U-shaped.
8 of 9
Describe a what a ribbon lake is and how it is formed.
Ribbon lakes are long and thin. They form when the glacier erodes more deeply than in the rest of the valley (this is usually because of thicker/heavier ice).
