Oceans of the World

An ocean is a very large body of salt water. Earth has five major oceans. The five oceans together cover almost three-fourths of the earth’s surface. That means that if you had a box that was supposed to be the whole world and you divided it into four equal parts, three of them would be the part that is covered with water, and one of the would be the part of the world that would be land. See the picture below:

All of the blue part of the box would be water, and the green part would be land. That really is a lot of water!

The five major oceans all run together at some point. The five major oceans of Earth are:

Pacific Ocean—The Pacific Ocean is the largest ocean in the world. It goes all the way from Asia to North and South America, and it goes from the Bering Strait between Alaska and Russia which joins it to the Arctic Ocean, all the way south where it joins the Southern Ocean.

Atlantic Ocean—The Atlantic Ocean is the second-largest ocean in the world. It goes all the way from Europe and Africa to North and South America, and it goes from the Arctic Ocean in the north, all the way south where it joins the Southern Ocean.

Indian Ocean—The Indian Ocean is the third-largest ocean in the world. It goes from Africa to Australia and some of the islands of Indonesia and from Asia on the north, all the way south where it joins the Southern Ocean.

Southern Ocean—The Southern Ocean is the fourth-largest ocean in the world. It goes all the way around the continent of Antarctica and joins the Indian, Atlantic, and Pacific Oceans as it goes north.

Arctic Ocean—The Arctic Ocean is the smallest ocean in the world. It is very cold and icy. The North Pole is near the center of the Arctic Ocean. It goes south and touches North America, Europe, and Asia.
