The correct answer is 2 and 3 only. Important Points In oceanography, a marginal sea is a sea partially enclosed by islands, archipelagos, or peninsulas. Some of the major marginal seas include the Arabian Sea, Baltic Sea, Bay of Bengal, Bering Sea, Black Sea, Gulf of California, Gulf of Mexico, Mediterranean Sea, Red Sea, and all four of the Siberian Seas (Barents, Kara, Laptev, and East Siberian). Hence, statement 1 is correct. The primary differences between marginal seas and open oceans are associated with depth and proximity to landmasses. Marginal seas, which are generally shallower than open oceans, are more influenced by human activities, river runoff, climate, and water circulation. The Black Sea is an inland sea located between far-southeastern Europe and the far-western edges of the continent of Asia and the country of Turkey. Its bordering countries are Romania, Bulgaria, Ukraine, Russia, Georgia, and Turkey. The Black Sea drains into the Mediterranean Sea, via the Aegean Sea and various straits. Mistake Points The Bosphorus Strait connects it to the Sea of Marmara, and the Strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. Hence, statement 2 is NOT correct. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch. Hence, statement 3 is NOT correct. ​[ alt="Black sea" src="//storage.googleapis.com/tb-img/production/20/11/Black%20sea.PNG">
