I WONDER - Where Is The Largest Lake In The World?

The video discusses the Caspian Sea, the largest lake in the world, which borders five countries: Russia, Iran, Kazakhstan, Azerbaijan, and Turkmenistan. Despite being called a sea, it does not connect to an ocean. Over 130 rivers flow into it, with the Volga River being the largest. The Caspian Sea is located between Europe and Asia.
