SIBERIA is an extensive geographicalregion,and by the broadest definition is also known as North Asia.Siberia has been historically part of Russia since the seventeenth century.
The territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific andArctic drainage basins.Siberia stretches southwards from the Arctic Ocean to the hills of north-centralKazakhstan and to the national borders of Mongolia and China.[1] Siberia accounts for 77% of Russia's land area (13.1 million square kilometres),but is home to just 27% (40 million people) of the country's
With an area of 13.1 million km² (5.1 million square miles),Siberia takes up roughly 77% of Russia's total territory.Major geographical zones include the West Siberian Plain and the Central Siberian Plateau.Siberia covers almost 10% of Earth's land surface (148,940,000 km²).While Siberia falls entirely within Asia,many authorities such as the UN geoscheme will not subdivide countries and will place all of Russia as part of Europe and/or Eastern Europe.
Eastern and central Sakha comprise numerous North-South mountain ranges of various ages.These mountains extend up to almost three thousand meters in elevation,but above a few hundred meters they are almost completely devoid of vegetation.The Verkhoyansk Range was extensively glaciated in the Pleistocene,but the climate was too dry for glaciation to extend to low elevations.At these low elevations are numerous valleys,many of them deep,and covered with larch forest,except in the extreme North,where the tundra dominates.Soils are mainly turbels (a type of gelisol).The active layer tends to be less than one meter deep,except near rivers.
The highest point in Siberia is the active volcano Klyuchevskaya Sopka,on the Kamchatka Peninsula.Its peak is at 4,649 meters (15,253 ft).
Siberia is extraordinarily rich in minerals,containing ores of almost all economically valuable metals—largely because of the absence of Quaternary glaciation outside highland areas.It has some of the world's largest deposits of nickel,gold,lead,coal,molybdenum,gypsum,diamonds,diopside,silver and zinc,as well as extensive unexploited resources of oil and natural gas.Around 70% of Russia's developed oil fields are in the Khanty-Mansiysk region.Russia contains about 40% of the world's known resources of nickel at the Norilsk deposit in Siberia.Norilsk Nickel is the world's biggest nickel and palladium producer.
Siberian agriculture is severely restricted by the short growing season of most of the region.However,in the southwest where soils are exceedingly fertile black earths and the climate is a little more moderate,there is extensive cropping of wheat,barley,rye and potatoes,along with the grazing of large numbers of sheep and cattle.Elsewhere food production,owing to the poor fertility of the podzolic soils and the extremely short growing seasons,is restricted to the herding of reindeer in the tundra—which has been practiced by natives for over 10,000 years.Siberia has the world's largest forests.Timber remains an important source of revenue,even though many forests in the east have been logged much more rapidly than they are able to recover.The Sea of Okhotsk is one of the two or three richest fisheries in the world owing to its cold currents and very large tidal ranges,and thus Siberia produces over 10% of the world's annual fish catch,although fishing has declined somewhat since the collapse of the USSR.
