The West Siberian Plain is one of the greatest plains in the world. From north to south, it stretches for two and a half thousand kilometers, from west to east - a little less than two thousand. Its natural boundaries are: in the north - the seas of the Arctic Ocean, in the south - the Kazakh hills, in the west - the Urals and in the east - the Yenisei. The area of the plain is slightly less than three million square kilometers.
There are many deposits of various minerals here. But the main ones are hydrocarbons. The West Siberian Plain is the largest oil and gas bearing region of the Russian Federation and one of the largest in the world.
The large area and relative uniformity of the relief have caused the West Siberian Plain to include a large number of natural and climatic zones with a clear distribution from north to south. In areasadjacent to the Arctic Ocean, the dominant type of landscape is tundra with extensive wetlands. To the south, the character of the terrain is gradually changing. The tundra is replaced by forest-tundra with islands of low trees, to the south - taiga, consisting of dark coniferous trees, and further south is a belt of deciduous forests. At about the fifty-fifth parallel, the forests are diluted with steppe and fields, and there is almost no forest on the border with Kazakhstan, with the exception of the eastern regions of the plain.
In the seventies of the last century, the West Siberian Plain was subjected to strong anthropogenic impact. The impact continues to this day. This is due to the beginning of mass development of hydrocarbon deposits. But even now, vast areas outside of hydrocarbon deposits remain wild, as they were many years ago.
Natural conditions even at the same latitude are slightly different here. This is due to the fact that the West Siberian Plain, whose climate depends on the presence of a natural barrier (the Urals) that protects against warm westerly winds, lies in the region of transition from a temperate continental climate to a sharply continental one. And if the difference between the prevailing summer and winter temperatures in the regions adjacent to the Urals is less pronounced, then the left bank of the Yenisei is already a territory where a full-fledged sharply continental climate reigns.
There are no large elevation changes here, but still there are small hills, lowlands and swamps, which are especially rich in the West Siberian Plain. The relief seems to consist of elements (Vasyugan plain, Kulunda ranina, Baraba lowland, and so on), competing with each other - who is lower. And only in the north are Siberian Uvals -
a ridge nine hundred kilometers long, the highest point of which barely exceeded three hundred meters.
Separately, it must be said about the rivers of the West Siberian Plain. Almost the entire territory is occupied by the Ob basin with the main tributary, the Irtysh. The eastern part of the plain is included in the Yenisei basin. The territory is provided with water resources in abundance. But due to the flat nature of the river and the absence of elevation changes, there are practically no large hydroelectric power stations on it, with the exception of Novosibirsk, located in the upper reaches. Despite the huge potential, the construction of a hydroelectric power station on the Ob below Novosibirsk is impossible, since in this case a huge territory will be flooded.

Siberian cedar: description, planting and cultivation. What is Siberian cedar resin and what is its use?
Siberian cedar is distinguished by a brown-gray trunk, which is covered with fissured scaly bark (mainly in old trees). A feature of this evergreen coniferous tree is whorled branching. It has a very short growing season (40-45 days a year), so the Siberian cedar is one of the slow-growing and shade-tolerant species. Siberian cedar is planted taking into account the appropriate distance between trees (8 m). The official name of resin is Siberian cedar resin
Rodents: all kinds and other useful information
Most representatives of the rodent family, despite the widespread bad opinion about them, are useful to people. They exterminate insects and prevent weeds from growing, thereby maintaining the purity of the forest. And, of course, rodents are also suppliers of valuable and beautiful fur. It is impossible to list all types of these animals in one article, but we will try to highlight the most important points
West Siberian Plain: minerals, location, description
In the world there is hardly such a huge space with a flat relief as the West Siberian Plain. Minerals deposited in this territory were discovered in 1960
Ecological problems of the West Siberian Plain. Problems of nature and man in Western Siberia
Today, in almost all countries of the world, the issue of environmental safety is particularly acute. There is nothing surprising in this: the rash and greedy use of natural resources has led to the fact that today there is a danger of extinction not only of most of the animals, but also of the human race itself
Ecological problems of the Russian Plain. Problems of rational use of resources of the Russian Plain
The East European Plain is located on the continent of Eurasia and ranks second in the world in terms of area after the Amazonian Plain. The second name of the East European Plain is Russian. This is due to the fact that a significant part of it is occupied by the state of Russia. It is in this territory that most of the population of the country is concentrated and the largest cities are located
