GEOLOGY

Detailed explanation-1: -Southern Ocean, also called Antarctic Ocean, body of salt water covering approximately one-sixteenth of Earth’s total ocean area. The Southern Ocean is made up of the portions of the world ocean south of the Pacific, Atlantic, and Indian oceans and their tributary seas surrounding Antarctica below 60° S.

Detailed explanation-2: -There is only one global ocean. 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.

Detailed explanation-3: -The Indian Ocean, the third largest, extends northward from the Southern Ocean to India, the Arabian Peninsula, and Southeast Asia in Asia, and between Africa in the west and Australia in the east. The Indian Ocean joins the Pacific Ocean to the east, near Australia. The Arctic Ocean is the smallest of the five.

Detailed explanation-4: -In the southwest it joins the Atlantic Ocean south of the southern tip of Africa, and to the east and southeast its waters mingle with those of the Pacific Ocean.
