Siberia spans over 13 million square kilometers (5.1 million sq mi)—77% of Russia—stretching from the Urals to the Pacific, and from the Arctic Ocean to the borders of China and Central Asia. It is the world's largest plain (the West Siberian Plain) and a mosaic of distinct terrains:
Siberia is drained by three of the world's longest rivers:
Long, brutal winters (January averages: -15°C to -35°C) and short, warm summers (July: 15°C to 25°C). The vast landmass, far from oceanic moderation, creates this intense seasonality.
Iconic species include brown bears, wolves, moose, reindeer, and the critically endangered Siberian tiger and Amur leopard in the Far East.
A multiethnic population (Russians, Tatars, Evenks, Buryats, Yakuts, and others) concentrated in southern cities like Novosibirsk, Omsk, and Krasnoyarsk.
