Russia, the world's largest country, covers one-tenth of Earth's landmass. Spanning 11 time zones across Europe and Asia, it boasts coastlines on the Atlantic, Pacific, and Arctic oceans. Its diverse landscape encompasses deserts, frozen coastlines, mountains, and marshes. Vast steppes, treeless plains, dominate much of the country, while Siberia, comprising three-quarters of Russia, is characterized by expansive taiga forests. Russia is home to approximately 100,000 rivers, including some of the world's longest and most powerful. It also features numerous lakes, including Europe's two largest, Ladoga and Onega. Notably, Lake Baikal in Siberia holds more water than any other lake on Earth.
