This cover is very resistant and can tolerate drastic environmental conditions such as drought, soil-heaving, seasonal waterlogging and geliturbation. Its elasticity is also adapted to cryogenic deformation, giving the soil surface the appearance of elephant skin.
Furthermore, the accumulation of amorphous compounds (mineral or organic) results in an increase in the geliexpansibility of the material, and thus soil formation processes may mean that sands that were initially untouched are later affected by geliturbation.
All the differences in the raising of the ice are thus expressed below, giving rise to geliturbations. The microrelief is caused by the expression on the surface of the differential raising.
