The [horizon](/source/Soil_horizon) differentiation is weak. This is evident from weak, mostly brownish discolouration and/or structure formation in the [soil profile](/source/soil_profile). thumb|400px|right|Distribution of Cambisols Cambisols are developed in medium and fine-textured materials derived from a wide range of rocks, mostly in [alluvial](/source/alluvial), [colluvial](/source/colluvium) and [aeolian deposits](/source/Aeolian_processes). Most of these soils make good agricultural land and are intensively used. Cambisols in temperate [climate](/source/climate)s are among the most productive soils on earth. Cambisols cover an estimated 15 million square kilometres worldwide. They are well represented in [temperate](/source/temperate_climate) and boreal regions that were under the influence of [glaciation](/source/glaciation) during the [Pleistocene](/source/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, but they are common in areas with active [erosion](/source/erosion) where they may occur in association with mature tropical soils. == See also == *[Pedogenesis](/source/Pedogenesis) *[Pedology (soil study)](/source/Pedology_(soil_study)) *[Soil classification](/source/Soil_classification) == References == {{reflist}} ==Further reading== * W.
