The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia. It lies to the east of the Balkans in Southeast Europe, south of the East European Plain in Eastern Europe; and north of Anatolia and west of the Caucasus, both in Western Asia.
Why Black Sea is called Black Sea?
Another theory suggests that the name Black Sea came from the storms during winter that make the water in the Sea appear black. Another theory suggests that the objects that drown in the water get a black sludge covering after a period of time and discovery of such items across the sea may have given the Sea its name.
