If all the water is collected, it will only be a small drop compared to the globe.
About 70 percent of the earth’s surface is covered by water. But the total volume of water is only 0.13 percent of the Earth’s.
To give a visual idea of how little water actually exists, the U.S. The Geological Survey produced an image in which the soil was drained of all water collected into a spherical reservoir located over the United States.
The water drop will then have a diameter of 1,385 kilometers, giving a volume of 1.4 billion cubic kilometers.
“It holds all the water that is in the seas, lakes, rivers, glaciers, soil, air and even in yourself and your dog,” writes U.S. Geological Survey.
Here are some more facts about the Earth’s water:
96.5 percent are found in the seas.
2.5 percent is fresh water. Of this, 30 percent are groundwater and 69 percent are bound in glaciers and ice.
Only one percent of all water is useful to humans. 99 percent of it is groundwater.
