Siberian Federal District
Geographic Russian Siberia
|Region||North Asia, Eurasia|
|• Total||13,100,000 km2 (5,100,000 sq mi)|
|• Density||2.75/km2 (7.12/sq mi)|
The territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins. The Yenisei River conditionally divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-central Kazakhstan and to the national borders of Mongolia and China.
With an area of 13.1 million square kilometres (5,100,000 sq mi), Siberia accounts for 77% of Russia's land area, but it is home to approximately 36 million people—27% of the country's population. This is equivalent to an average population density of about 3 inhabitants per square kilometre (7.8/sq mi) (approximately equal to that of Australia), making Siberia one of the most sparsely populated regions on Earth. If it were a country by itself, it would still be the largest country in area, but in population it would be the world's 35th-largest and Asia's 14th-largest.
Worldwide, Siberia is well known primarily for its long, harsh winters, with a January average of −25 °C (−13 °F), as well as its extensive history of use by Russian and Soviet governments as a place for prisons, labor camps, and internal exile.
With an area of 13.1 million square kilometres (5,100,000 sq mi), Siberia makes up roughly 77% of Russia's total territory and almost 9% of Earth's land surface (148,940,000 km2, 57,510,000 sq mi). 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. Major geographical zones include the West Siberian Plain and the Central Siberian Plateau.
Eastern and central Sakha comprises numerous north-south mountain ranges of various ages. These mountains extend up to almost 3,000 metres (9,800 ft), but above a few hundred metres 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 metre deep, except near rivers.

Lakes and rivers
The West Siberian Plain consists mostly of Cenozoic alluvial deposits and is somewhat flat. Many deposits on this plain result from ice dams which produced a large glacial lake. This mid- to late-Pleistocene lake blocked the northward flow of the Ob and Yenisei rivers, resulting in a redirection southwest into the Caspian and Aral seas via the Turgai Valley. The area is very swampy, and soils are mostly peaty histosols and, in the treeless northern part, histels. In the south of the plain, where permafrost is largely absent, rich grasslands that are an extension of the Kazakh Steppe formed the original vegetation, most of which is no longer visible.[why?]
The Central Siberian Plateau is an ancient craton (sometimes named Angaraland) that formed an independent continent before the Permian (see the Siberian continent). It is exceptionally rich in minerals, containing large deposits of gold, diamonds, and ores of manganese, lead, zinc, nickel, cobalt and molybdenum. Much of the area includes the Siberian Traps—a large igneous province. This massive eruptive period was approximately coincident with the Permian–Triassic extinction event. The volcanic event is said to be the largest known volcanic eruption in Earth's history. Only the extreme northwest was glaciated during the Quaternary, but almost all is under exceptionally deep permafrost, and the only tree that can thrive, despite the warm summers, is the deciduous Siberian Larch (Larix sibirica) with its very shallow roots. Outside the extreme northwest, the taiga is dominant, covering a significant fraction of the entirety of Siberia. Soils here are mainly turbels, giving way to spodosols where the active layer becomes thicker and the ice content lower.
The Lena-Tunguska petroleum province includes the Central Siberian platform (some authors refer to it as the Eastern Siberian platform), bounded on the northeast and east by the Late Carboniferous through Jurassic Verkhoyansk foldbelt, on the northwest by the Paleozoic Taymr foldbelt, and on the southeast, south and southwest by the Middle Silurian to Middle Devonian Baykalian foldbelt. A regional geologic reconnaissance study begun in 1932, followed by surface and subsurface mapping, revealed the Markova-Angara Arch (anticline). This led to the discovery of the Markovo Oil Field in 1962 with the Markovo 1 well, which produced from the Early Cambrian Osa Horizon bar-sandstone at a depth of 2,156 metres (7,073 ft). The Sredne-Botuobin Gas Field was discovered in 1970, producing from the Osa and the Proterozoic Parfenovo Horizon. The Yaraktin Oil Field was discovered in 1971, producing from the Vendian Yaraktin Horizon at depths of up to 1,750 metres (5,740 ft), which lies below Permian to Lower Jurassic basalt traps.

|Vegetation in Siberia is mostly taiga, with a tundra belt on the northern fringe, and a temperate forest zone in the south.|
The climate of Siberia varies dramatically, but it typically has short summers and long, brutally cold winters. On the north coast, north of the Arctic Circle, there is a very short (about one month long) summer.
Almost all the population lives in the south, along the Trans-Siberian Railway. The climate in this southernmost part is Humid continental climate (Köppen Dfb) with cold winters but fairly warm summers lasting at least four months. The annual average is about 0.5 °C (32.9 °F). January averages about −20 °C (−4 °F) and July about +19 °C (66 °F) while daytime temperatures in summer typically are above 20 °C (68 °F). With a reliable growing season, an abundance of sunshine and exceedingly fertile chernozem soils, southern Siberia is good enough for profitable agriculture, as was proven in the early 20th century.
By far the most commonly occurring climate in Siberia is continental subarctic (Koppen Dfc or Dwc), with the annual average temperature about −5 °C (23 °F) and an average for January of −25 °C (−13 °F) and an average for July of +17 °C (63 °F), although this varies considerably, with a July average about 10 °C (50 °F) in the taiga–tundra ecotone. The Business oriented website and blog Business Insider lists Verkhoyansk and Oymyakon, in Siberia's Sakha Republic, as being in competition for the title of the Northern Hemisphere's Pole of Cold. Oymyakon is a village which recorded a temperature of −67.7 °C (−89.9 °F) on 6 February 1933. Verkhoyansk, a town further north and further inland, recorded a temperature of −69.8 °C (−93.6 °F) for three consecutive nights: 5, 6 and 7 February 1933. Each town is alternately considered the Northern Hemisphere's Pole of Cold, meaning the coldest inhabited point in the Northern hemisphere. Each town also frequently reaches 86 °F (30 °C) in the summer, giving them, and much of the rest of Russian Siberia, the world's greatest temperature variation between summer's highs and winter's lows, often being well over 170–180+°F (94–100+°C) between the seasons.
Southwesterly winds bring warm air from Central Asia and the Middle East. The climate in West Siberia (Omsk, Novosibirsk) is several degrees warmer than in the East (Irkutsk, Chita) where in the north an extreme winter subarctic climate (Köppen Dfd or Dwd) prevails. But summer temperatures in other regions can reach +38 °C (100 °F). In general, Sakha is the coldest Siberian region, and the basin of the Yana River has the lowest temperatures of all, with permafrost reaching 1,493 metres (4,898 ft). Nevertheless, as far as Imperial Russian plans of settlement were concerned, cold was never viewed as an impediment. In the winter, southern Siberia sits near the center of the semi-permanent Siberian High, so winds are usually light in the winter.
Precipitation in Siberia is generally low, exceeding 500 millimetres (20 in) only in Kamchatka where moist winds flow from the Sea of Okhotsk onto high mountains – producing the region's only major glaciers, though volcanic eruptions and low summer temperatures allow limited forests to grow. Precipitation is high also in most of Primorye in the extreme south where monsoonal influences can produce quite heavy summer rainfall.

Borders and administrative division
The term "Siberia" has a long history. Its meaning has gradually changed during ages. Historically, Siberia was defined as the whole part of Russia to the east of Ural Mountains, including the Russian Far East. According to this definition, Siberia extended eastward from the Ural Mountains to the Pacific coast, and southward from the Arctic Ocean to the border of Russian Central Asia and the national borders of both Mongolia and China.
Soviet-era sources (Great Soviet Encyclopedia and others) and modern Russian ones usually define Siberia as a region extending eastward from the Ural Mountains to the watershed between Pacific and Arctic drainage basins, and southward from the Arctic Ocean to the hills of north-central Kazakhstan and the national borders of both Mongolia and China. By this definition, Siberia includes the federal subjects of the Siberian Federal District, and some of the Ural Federal District, as well as Sakha (Yakutia) Republic, which is a part of the Far Eastern Federal District. Geographically, this definition includes subdivisions of several other subjects of Urals and Far Eastern federal districts, but they are not included administratively. This definition excludes Sverdlovsk Oblast and Chelyabinsk Oblast, both of which are included in some wider definitions of Siberia.
Other sources may use either a somewhat wider definition that states the Pacific coast, not the watershed, is the eastern boundary (thus including the whole Russian Far East) or a somewhat narrower one that limits Siberia to the Siberian Federal District (thus excluding all subjects of other districts). In Russian, the word for Siberia is used as a substitute for the name of the federal district by those who live in the district itself and less commonly used to denote the federal district by people residing outside of it.

The most populous city of Siberia, as well as the third most populous city of Russia, is the city of Novosibirsk. Other major cities include:
Wider definitions of Siberia also include:
- Yekaterinburg – Some sources such as Encyclopædia Britannica include this city as it lies in the Ural Mountains. Inhabitants have distanced themselves though saying that there is a difference between Siberian and Urals culture.
Siberia is extraordinarily rich in minerals, containing ores of almost all economically valuable metals. 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.
While the development of renewable energy in Russia is held back by the lack of a conducive government policy framework, Siberia still offers special opportunities for off-grid renewable energy developments. Remote parts of Siberia are too costly to connect to central electricity and gas grids, and have therefore historically been supplied with costly diesel, sometimes flown in by helicopter. In such cases renewable energy is often cheaper.
