We think of Earth being the water planet, and at its surface it is. However, it is but a very thin sheen of water that blankets the surface. Above is a visualization of the all of the water of Earth gathered into a globe and compared to the size of what remains.
As the Gizmodo article Truly Awesome Picture Perfectly Shows How Little Water There Is On Earth explains:
This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) , with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.
Makes me thirsty just looking at it. Via Linkiest's, May 14, 2012 items.
