The name of the sea located between Europe and Asia is the Caspian Sea. It is the world's largest enclosed inland body of water and is bordered by five countries: Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. Despite its name, the Caspian Sea is technically a lake, and it is significant for its biodiversity, resource reserves, and historical trade routes. The sea is crucial for regional economies, particularly for oil and gas extraction, fishing, and tourism industries.
