Nivation


Set of processes, operating beneath or next to snow, believed to be responsible for the development of the hollows in which snow collects. It is also thought to play a role in the early formation of corries. The processes involved include freeze–thaw (weathering by the alternate freezing and melting of ice), mass movement (the downhill movement of substances under gravity), and erosion by meltwater.
