Which ocean encircles the Antarctic region and is often referred to by a specific name?

• A. Southern Ocean
• B. Arctic Ocean
• C. Pacific Ocean
• D. Atlantic Ocean

Answer: (A)

The ocean that surrounds Antarctica is called the Southern Ocean. It’s unique because it completely encircles the continent, connecting the Atlantic, Pacific, and Indian Oceans through the Antarctic Circumpolar Current. This current helps mix waters around the pole and plays a big role in climate and ocean circulation. Other oceans don't surround Antarctica—the Arctic Ocean sits around the North Pole, while the Pacific and Atlantic lie to the sides. Modern naming uses Southern Ocean for this surrounding body of water, though some older sources used other terms.
