Detailed explanation-1: -The oceans are, by far, the largest storehouse of water on earth-over 96% of all of Earth’s water exists in the oceans. Not only do the oceans provide evaporated water to the water cycle, they also allow water to move all around the globe as ocean currents.

Detailed explanation-2: -About 97 percent of Earth’s water is in the ocean. Of the tiny percentage that’s not in the ocean, about two percent is frozen up in glaciers and ice caps. Less than one percent of all the water on Earth is fresh. A tiny fraction of water exists as water vapor in our atmosphere.

Detailed explanation-3: -The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins.

Detailed explanation-4: -Most of the water on the Earth’s surface is found in oceans and seas, which constitute about 97% of the water on Earth. The rest 3% is present in rivers, glaciers and underground water.

Detailed explanation-5: -All of this water is not distributed equally over the Earth; 61% of the Northern Hemisphere is covered by oceans, while in the Southern Hemisphere the oceans cover 81% of the surface area (Figure 1.1. 1). Figure 1.1.
