North 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 8.8% of Earth's total land area; and is the largest subregion of Asia by area, but is also the least populated, with a population of around 37 million, accounting for merely 0.74% of Asia's population.
Topographically, the region is dominated by the Eurasian Plate, except for its eastern part, which lies on the North American, Amurian, and Okhotsk Plates. It is divided by three major plains: the West Siberian Plain, Central Siberian Plateau, and Verhoyansk-Chukotka collision zone. The Uralian orogeny in the west raised Ural Mountains, the informal boundary between Asia and Europe. Tectonic and volcanic activities are frequently occurred in the eastern part of the region as part of the Ring of Fire, evidenced by the formation of island arcs such as the Kuril Islands and ultra-prominent peaks such as Klyuchevskaya Sopka, Kronotsky, and Koryaksky. The central part of North Asia is a large igneous province called the Siberian Traps, formed by a massive eruption occurred 250 million years ago. The formation of the traps coincided with the Permian–Triassic extinction event.
North Asia, geographically, is a subregion of Asia. However, because it was colonised and incorporated into Russia, many international organisations either consider or classify North Asia as part of Eastern Europe along with European Russia. European cultural influences, specifically Russian, are predominant in the entire region, due to it experiencing Russian emigration from Europe starting from the 18th century. Slavs and other Indo-Europeans make up the vast majority of North Asia's population, and over 85% of the region's population is of European descent.
History
The region was first populated by hominins in the Late Pleistocene, approximately 100,000 years ago, and modern humans are confirmed to arrived in the region by 45,000 years ago with the first humans in the region having West Eurasian origins. Its Neolithic culture is characterized by characteristic stone production techniques and the presence of pottery of eastern origin. The Bronze Age began during the 3rd millennium BCE, with influences of Indo-Iranian cultures as evidenced by the Andronovo culture. During the 1st millennium BCE, polities such as the Scythians and Xiongnus emerged in the region, who often clashed with its Persian and Chinese neighbors in the south. The Göktürks dominated southern Siberia during the 1st millennium CE, while in the early 2nd millennium, the Mongol Empire and its successor states ruled the region. The Khanate of Sibir was one of the last independent Turkic states in North Asia before its conquest by the Tsardom of Russia in the 16th century. Russia would then gradually annex the region into its territory until the Convention of Peking was signed in 1860. After the October Revolution in 1917, the region was contested between the Bolsheviks and Whites until the Soviet Union asserted full control in 1923. The collapse of the Soviet Union in 1991 left Russia as the administrator of the region.
Geography
For geographic and statistical reasons, the UN geoscheme and various other classification schemes will not subdivide countries, and thus place all of Russia in the Europe or Eastern Europe subregion.
There are no mountain chains in Northern Asia to prevent air currents from the Arctic flowing down over the plains of Siberia and Turkestan.
The plateau and plains of Northern Asia comprise the West Siberian lowlands; the Angara Shield, with the Taimyr Peninsula, the coastal lowlands (North Siberian Lowland and East Siberian Lowland), the Central Siberian Plateau, (Putorana Plateau, Lena Plateau, Anabar Plateau, Tunguska Plateau, Vilyuy Plateau, and the Lena-Angara Plateau); and the Lena–Vilyuy Lowland. Western Siberia is usually regarded as the Northwest Asia, Kazakhstan also sometimes included there. However, Northwest Asia sometimes refers to Caucasus or nearby provinces.
Geomorphology
The geomorphology of Northern Asia in general is imperfectly known, although the deposits and mountain ranges are well known.
