Russia is home to some of the world's most impressive mountain ranges, including the Ural Mountains and the Caucasus Mountains. The Ural Mountains, which stretch from the Arctic Ocean to the Caspian Sea, serve as a natural boundary between Europe and Asia. The Caucasus Mountains, located between the Black Sea and the Caspian Sea, include Mount Elbrus, the highest peak in Europe. Another significant range is the Sayan Mountains, found in southern Siberia, known for their rugged terrain and diverse ecosystems. The Altai Mountains, located in the southeastern part of the country, are famous for their stunning landscapes and rich biodiversity. These mountain ranges play a crucial role in Russia's geography and climate.
