Asie du Nord
Résumé
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 33 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.
