The earth's water is mostly made up of oceans, which is 97% of earths water, but the other 3% is earths glaciers. hope this helped, have an amazing day :)
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. Hope this helps
