The division between Europe and Asia in Russia is generally considered to be the Ural Mountains, which run from north to south across the country. The areas west of the Urals are considered to be part of Europe, while the areas east of the Urals are considered to be part of Asia.
However, there is no precise geographic boundary between Europe and Asia, and some definitions may vary. Some consider the Caspian Sea and the Caucasus Mountains to be the dividing line, while others may draw the line differently based on cultural, historical, or political factors.
In summary, Russia is a transcontinental country that straddles both Europe and Asia, with its territory and population distributed across both continents. The Ural Mountains are often considered as the dividing line between the two continents, but the exact boundary may vary depending on different perspectives and definitions.
