GEOLOGY

Detailed explanation-1: -About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water.

Detailed explanation-2: -The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into four distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans.

Detailed explanation-3: -Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth’s surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years-most of its existence.

Detailed explanation-4: -71% of the Earth’s surface is covered with water. 97% of which is in the form of oceans. The water in the oceans is salty.

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. Q. People use a lot of water everyday, the amount of water on the Earth doesn’t change due to water .
