There is only one ocean on the planet, but it is divided into five sections or five oceans. The five sections of the ocean are the Atlantic, Pacific, Southern, Arctic and Indian oceans.
The Atlantic Ocean, including both the northern and southern sections, stretches from the eastern seaboard of the Americas, to the western seaboard of Europe and Africa. The Pacific Ocean reaches from the western seaboard of the Americas, all the way to Asia and Australia. The Indian Ocean reaches from the western coast of Africa, along the southern edge of India, Australia and Asia, all the way down to where it meets the Southern ocean. The Southern and the Arctic oceans surround the poles.
