Sainmhíniú pedologic process that consists of the mixing of soil layers most commonly due to repeated freeze‐thaw processes and is dominant in permafrost areas, while some cryoturbation may occur in areas of seasonal frost, and is often accompanied by patterned ground, including sorted and nonsorted circles, nets, polygons, stripes, and steps Tagairt "COM-Terminology Coordination, based on: J.G Bockheim, C Tarnocai. 'Recognition of cryoturbation for classifying permafrost-affected soils' (14.3.2024). Geoderma Volume 81, Issues 3–4, January 1998, Pages 281-293"
Nóta "Two models have been suggested to explain the cryoturbation process: - in the cryostatic model, freezing fronts moving downward from the surface and upward from the permafrost table cause pressure on the unfrozen material between the fronts; - in the convective cell equilibrium model, heave- subsidence cycles at the bottom move upward and inward. This results in a slow upward cell-type circulation."

Nóta The basic cause of the disintegration of materials acted upon by low temperatures is that the water filling the pores of the material expands when it freezes. Frost resistance depends primarily on the structure of the material: the larger the pores that water can penetrate, the lower frost resistance will be.
