Major Rivers of Russia: Volga, Ob, Yenisei, Lena, Amur

Russia's vast territory is drained by several giant rivers:

1. Volga: Europe's longest (3,500+ km); flows to Caspian Sea.
2. Ob: World's 7th longest; longest in Russia; forms Ob-Irtysh system.
3. Yenisei: 5th longest globally; flows entirely in Russia to Kara Sea.
4. Lena: 11th longest; entirely in Russia to Laptev Sea.
5. Amur: Forms Russia-China border; empties into Sea of Okhotsk.

These rivers have been vital for transport, trade, and development.
