Frost

Abstract

Though frost itself forms from vapor deposition, many of the periglacial processes and associated landforms that incorporate frost within their names are more commonly associated with ice formed by freezing of liquid water. Thin films of premelted water that remain unfrozen at the interfaces between ice and sediment particles at subzero temperatures enable significant water redistribution. This behavior leads to frost action, frost creep, frost heave, and the formation of numerous geomorphic features.
