Detailed explanation-1: -Of all the water that exists on our planet, roughly 97% is saltwater and less than 3% is freshwater. Most of Earth’s freshwater is frozen in glaciers, ice caps, or is deep underground in aquifers.

Detailed explanation-2: -The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.

Detailed explanation-3: -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-4: -About 97 percent of Earth’s water is in the ocean. 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.

Detailed explanation-5: -By far, most of the hydrosphere is salt water – around 97 percent – but the 3 percent that is fresh is critical for terrestrial and fresh water species.
