Central Siberian Plateau
Geographers traditionally divide the vast territory of Russia into five natural zones: the tundra zone; the Taiga, or forest, zone; the steppe, or plains, zone; the arid zone; and the mountain zone. Most of Russia consists of two plains (the East European Plain and the West Siberian Plain), three lowlands (the North Siberian, the Central Yakutian and the East Siberian), two plateaus (the Central Siberian Plateau and the Lena Plateau), and two systems of mountainous areas (the East Siberian Mountains in far northeastern Siberia and the South Siberian Mountains along the southern border).
