Geography freeze thaw weathering
WebFrost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice.The term serves as an umbrella term for a variety of processes such as frost shattering, frost wedging and cryofracturing. The process may act on a wide range of spatial and temporal scales, from minutes to …
