Description :
Nivation is generally associated with the weathering and mass movement processes stemming from late-lying seasonal snow and the ensuing landforms. As a process suite it invokes mechanisms such as freeze-thaw weathering and solifluction. Cryoplanation also invokes a process suite, but one that also embraces nivation. Research in the last 2 or 3 decades has begun to provide a much sharper definition of nivation, but the available information is still inadequate for a central mechanism in periglacial landscapes. A case is presented for viewing nivation and cryoplanation as a single process spectrum much in need of state-of-the-art research.
