GENERAL KNOWLEDGE

Detailed explanation-1: -Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries-including the United States-now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known. The Southern Ocean is the ‘newest’ named ocean.

Detailed explanation-2: -The geographers have separated the maritime portion of the earth into five oceans, in particular the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. The different oceans, gulf, bays and different deltas are portions of these five enormous oceans.

Detailed explanation-3: -National Geographic decided to designate the Antarctic waters as its own ocean (instead of merely southern parts the Atlantic, Indian and Pacific) to bring awareness to, and promote conservation of the waters. But also because of its unique attributes, which scientists and geographers have long recognized.

Detailed explanation-4: -The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into four distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans.

Detailed explanation-5: -The Earth has five oceans, including the Arctic, Atlantic, Indian, Pacific and Antarctic (Southern).
