Formation of a Corrie
Step 1: Neve Formation
Snow accumulates in a hollow, usually facing North East. This snow withstands summer temperatures and builds up in layers. The increasing weight of the snow compacts lower layers to form Neve.
Step 2: Nivation
Nivation – a combination of freeze-thaw weathering and melt water erosion - deepens the hollow.
Small amounts of biological and chemical weathering occur below the glacier where temperatures are warmer and the ground is moist.
Step 3: Further accumulation
Further accumulation results in the removal of air from the neve to form ice. The largest mass of ice is at the back of the glacier which pushes…
