Which of the following landlocked water bodies, bordered by countries such as Kazakhstan, Russia, Turkmenistan, Azerbaijan, and Iran, is technically classified as the largest inland body of water on Earth?

💡 Solution & Explanation

The Caspian Sea is an enclosed endorheic basin that holds the largest surface area of any inland body of water globally, earning it the designation of a sea despite lacking oceanic connection. Lake Baikal is the deepest freshwater lake containing the greatest volume, Lake Superior is the largest freshwater lake by surface area in North America, and the Aral Sea has undergone severe shrinkage due to irrigation diversions. Caspian basin sediments contain vast reserves of offshore petroleum and natural gas resources. Sturgeon populations in these saline waters are famous for caviar production.
