| Comment |
Mass wasting includes slow displacements such as frost creep, gelifluction or solifluction, and more rapid movements such as earthflows or active-layer failures. It does not include crustal displacements resulting from tectonic activity or those movements where material is carried directly by an active transporting medium, such as glacial ice, snow, water or air. In permafrost areas, mass wasting is not limited to the active layer; it can include displacements caused by the formation and creep of ground ice within permafrost. When frost heave is a component of frost creep, it is a mass wasting process.
