Nivation: The Key Facts

Process: Nivation

Freeze-thaw weathering, abrasion and possibly chemical weathering operating under the snow cause the underlying rock to disintegrate

As some of the snow melts in spring, the weathered particles are moved downslope by the meltwater and solifluction
Nivation Hollows


Landform: Nivation Hollows
Snow falls and is protected in small depressions or hollows. The snow is slowly compacted by further snow fall and melting into névé and eventually into firn. Weathering like abrasion and freeze-thaw weathering can weaken the soil underneath the snow and create slope failure. Meltwater and solifluction can wash the sediment out of the base of the snow patch, leaving a hollow behind.
