The U.S. Geological Survey has released a report saying how much water is really available on Earth!
If you took all the water on earth – in oceans, ice caps, lakes, rivers, groundwater, the atmosphere, and living things – and wrapped it into a sphere, it would have a diameter of about 860 miles. That 860-mile-high sphere is represented by the largest bubble in the picture, which stretches from Salt Lake City, Utah to Topeka, Kan. It has a volume of over 332 million cubic miles. If you popped this bubble with a giant pin, the resulting flow would cover the lower 48 states to a depth of about 107 miles.
