The distribution of soil types in Europe is linked to the latitude, but the zoning is often modified by climatic and topographical features. The tundra soil type is most common in Eastern Europe and in Iceland. The mountainosu tundra soils are typical for Scandinavia. Much more widespread in Europe are the podsolic soils, which are common in Northern Britain, Scandinavia, Finland, Poland, Northern Germany, Denmark and the northern part of Russia. In Central Europe the podsolic soils are replaced by brown soils (distributed from Britain to the eastern slopes of the Carpathian maountains, and in the mountains of Southern Europe). The black soils are widespread in the plains of Eastern Europe. Black soils are typical also for for the lower parts of the Danude valley (including the Danube hilly plane) and the middle parts of the Danube valley. In Sothern Europe the soil types are very diverse. In the Mediterranean regions of Europe where subtropical climate prevails and and the limestone is very common the the soils are mostly red (trerra rosa). In the cold and humid mountainous areas of the Alps, and generally in the high mountains in Europe the soils are peaty and podsolic.
