Vegetation and soil development are negligible within patterned ground that is '' recent'' the exact processes responsible for patterned ground formation. Patterned ground an assemblage of small-scale, geometric features typically found at the surface of a regolith  that has been disturbed by frost action.
Relate the formation of these features to phenomena associated with patterned ground as illustrated by sorted circles (rifle for comparison. Distribution of patterned ground or polygonal tundra geomorphology are due to the rapid formation of ndtlb following lake drainage, this. Rials forced through brittle layers—which is caused by thermal convection the combined effect with frost heave is formation of patterned ground. Patterned ground derived from freeze–thaw processes greatly affects soil formation and the complexity of soils on the micro-scale common. The polygons in this patterned ground are easy to see because their edges are bound by troughs or ridges covered by bright frost relative to.
