The [[Soil horizon|horizon]] differentiation is weak. This is evident from weak, mostly brownish discolouration and/or structure formation in the [[soil profile]].<ref name="WRB">[http://www.fao.org/ag/agl/agll/wrb/doc/wrb2007_corr.pdf FAO World Reference Base for Soil Resources, First update 2007]</ref>

Cambisols cover an estimated 15 million square kilometres worldwide. They are well represented in [[temperate climate|temperate]] and boreal regions that were under the influence of [[glaciation]] during the [[Pleistocene]], partly because the soil's parent [[material]] is still young, but also because soil formation is comparatively slow in the cool, northern regions. Cambisols are less common in the tropics and subtropics., Butbut they are common in areas with active [[erosion]] where they may occur in association with mature tropical soils.<ref name="WRB"/>
