Siberia is a vast region in northern Russia, covering about 5 million square miles. It stretches from the Ural Mountains in the west to the Pacific Ocean in the east. The landscape includes taiga forests, tundra, and mountain ranges, with the Siberian Taiga being one of the largest forested areas in the world. The region is characterized by its extreme climate, with long, harsh winters and short summers. Major rivers, such as the Lena and Ob, flow through Siberia, providing important waterways. Despite its size, Siberia has a low population density, with most inhabitants living in urban areas like Novosibirsk and Irkutsk.
