An ocean is a large body of salt water. The amount of salt in the ocean is about 3%. Oceans cover three fourths of the earth’s surface.

The ocean is always moving and changing. Water evaporates and dries up. Rain falls. Ocean currents move the water all of the time. Ocean water moves in a big circle from the center of the earth to the north and south poles. Then the water circles back again to the equator. Ocean currents can move icebergs from one part of the world to another.

The plants and animals that live in the ocean are a large resource for food. Scientists study ocean life. They are always discovering new forms of plants and animals.

There are five oceans in the world. They are the Atlantic, Pacific, Indian, Arctic, and Antarctic Oceans.

Sometimes people refer to the ocean as a sea of water. But a sea is enclosed by land. An ocean is not.
