Final answer:
The four main oceans are the Atlantic, Pacific, Indian, and Arctic oceans. The less known fifth ocean is the Southern Ocean, also known as the Antarctic Ocean.
Step-by-step explanation:
The names of the four main oceans are the Atlantic Ocean, the Pacific Ocean, the Indian Ocean, and the Arctic Ocean. The fifth and less known ocean is the Southern Ocean or Antarctic Ocean, which surrounds Antarctica. The Atlantic Ocean is bordered by regions such as Georgia and South Carolina in the USA, as well as the Chesapeake Bay.
The Pacific Ocean is vast, touching the western coasts of North and South America, and the eastern coasts of Asia and Australia. The Indian Ocean is bounded by countries in Southern Asia, including India, and stretches down to the southern coast of Australia and the eastern coast of Africa. The Arctic Ocean is located at the northernmost part of our planet. The Southern Ocean, recognized as a separate ocean by many scientists, encircles the continent of Antarctica and extends to the natural boundaries of the Atlantic, Pacific, and Indian Oceans.
