Köppen climate classificationThe Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification.
DenisovanThe Denisovans or Denisova hominins (prondɪˈniːsəvə ) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic. Denisovans are known from few physical remains; consequently, most of what is known about them comes from DNA evidence. No formal species name has been established pending more complete fossil material. The first identification of a Denisovan individual occurred in 2010, based on mitochondrial DNA (mtDNA) extracted from a juvenile female finger bone excavated from the Siberian Denisova Cave in the Altai Mountains in 2008.
NovosibirskNovosibirsk (ˌnoʊvəsɪˈbɪərsk,_-voʊs-, also UKˌnɒv-; Новосиби́рск, nəvəsjɪˈbjirsk) is the largest city and administrative centre of Novosibirsk Oblast and the Siberian Federal District in Russia. As of the 2021 Census, it had a population of 1,633,595, making it the most populous city in Siberia and the third-most populous city in Russia after Moscow and Saint Petersburg. The city is located in southwestern Siberia, on the banks of the Ob River.
IrtyshThe Irtysh (Ertis ügüzüg, Эрчис мөрөн, Erchis mörön, "erchleh", "twirl"; Иртыш; Ертіс, Ertis, هرتىس; Chinese: 额尔齐斯河, pinyin: É'ěrqísī hé, Xiao'erjing: عَعَرٿِسِ حْ; إيرتيش, Әртиш, Ertish; Иртеш, İrteş, يئرتئش, Siberian Tatar: Эйәртеш, Eya’rtes’) is a river in Russia, China, and Kazakhstan. It is the chief tributary of the Ob and is also the longest tributary river in the world. The river's source lies in the Mongolian Altai in Dzungaria (the northern part of Xinjiang, China) close to the border with Mongolia.
Altai MountainsThe Altai Mountains (ɑːlˈtaɪ), also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E.
North AsiaNorth Asia or Northern Asia, also referred to as Siberia, is the northern region of Asia, which is defined in geographical terms and is coextensive with the Asian part of Russia, and consists of three federal districts of Russia: Ural, Siberian, and the Far Eastern. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central and East Asia to its south; and by the Pacific Ocean and North America to its east. It covers an area of , or 8.
SteppeIn physical geography, a steppe (stɛp) is an ecoregion characterized by grassland plains without trees except near rivers and lakes. Steppe biomes may include: the montane grasslands and shrublands biome the temperate grasslands, savannas, and shrublands biome A steppe may be semi-arid that is covered with grass and/or with shrubs, depending on the season and latitude. The term "steppe climate" denotes a semi-arid climate, which is encountered in regions too dry to support a forest, but not dry enough to be a desert.
Trans-Siberian RailwayThe Trans-Siberian Railway, historically known as the Great Siberian Route and often shortened to Transsib, is a large railway system that connects European Russia to the Russian Far East. Spanning a length of over , it is the longest railway line in the world. It runs from the city of Moscow in the west to the city of Vladivostok in the east. During the period of the Russian Empire, government ministers—personally appointed by Alexander III and his son Nicholas II—supervised the building of the railway network between 1891 and 1916.
SiberiaSiberia (saɪˈbɪəriə ; Sibir', sjɪˈbjirj) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed part of the sovereign territory of Russia and its various predecessor states since the centuries-long conquest of Siberia, which began with the fall of the Khanate of Sibir in the late 16th century and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to only one-fifth of Russia's population.
