How much water is there on, in, and above the Earth?
Fresh groundwater and surface-water make up the bubble over Kentucky, which is about 252 miles in diameter. The sphere over Georgia represents fresh-water lakes and rivers (about 34.9 miles in diameter).
All Earth's water, liquid fresh water, and water in lakes and rivers
As you know, the Earth is a watery place. But just how much water exists on, in, and above our planet? About 70 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But 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.
Water is never sitting still, though, and thanks to the water cycle, our planet's water supply is constantly moving from one place to another and from one form to another. Things would get pretty stale without the water cycle! More?
