Detailed explanation-1: -71 percent of the earth’s surface is occupied by the seas and oceans.

Detailed explanation-2: -About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.

Detailed explanation-3: -The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface.

Detailed explanation-4: -The ocean covers more than 70 percent of the surface of our planet. It’s hard to imagine, but about 97 percent of the Earth’s water can be found in our ocean. Of the tiny percentage that’s not in the ocean, about two percent is frozen up in glaciers and ice caps.

Detailed explanation-5: -Water we use percolates through land or gets treated and enters a water body, from where it evaporates and comes down to the Earth in the form of precipitation. Thus water remains constant due to water cycle.
