Why do the areas around CaspianSea receive little rainfall?

The areas around the Caspian Sea receive little rainfall primarily due to their location in a rain shadow created by the surrounding mountain ranges, such as the Caucasus and the Ural Mountains. These mountains block moist air from the Atlantic Ocean, preventing it from reaching the inland regions. Additionally, the continental climate of the region leads to hot summers and cold winters, further contributing to low precipitation levels. As a result, the surrounding areas experience arid conditions.
