Siberia is a large region in Asian Russia that extends east from the Ural Mountains to the Pacific Ocean, and from the Arctic Ocean to the Mongolian border in the south. Siberia is divided into five geographical areas.
Siberia occupies approximately 5.2 million square miles, as of 2014. While Siberia is usually considered to have a cold climate, its climate is actually continental, with large temperature differences between summer and winter. Winter is long and cold, but Siberia's summers are fairly warm. Almost half of Siberia is forested. The current population of present-day Siberia is a mixture of different immigrant ethnicities, as well as people of various aboriginal backgrounds.
