How Much Water is on Earth


This is truly interesting. It’s a visualization done by the U.S. Geological Survey that show us exactly how much water this is on Earth compared to all the solid materials. The blue sphere represents all the water. Not as big as I thought, that’s for sure. Some of the quotes and states from the USGS follow:

  • The volume of all water would be about 332.5 million cubic miles (mi3), or 1,386 million cubic kilometers (km3). A cubic mile of water equals more than 1.1 trillion gallons. A cubic kilometer of water equals about 264 billion gallons.

    About 3,100 mi3 (12,900 km3) of water, mostly in the form of water vapor, is in the atmosphere at any one time. If it all fell as precipitation at once, the Earth would be covered with only about 1 inch of water.

    The 48 contiguous United States receives a total volume of about 4 mi3 (17.7 km3) of precipitation each day.

    Each day, 280 mi3 (1,170 km3)of water evaporate or transpire into the atmosphere.

    If all of the world’s water was poured on the United States, it would cover the land to a depth of 90 miles (145 kilometers).

    Of the freshwater on Earth, much more is stored in the ground than is available in lakes and rivers. More than 2,000,000 mi3 (8,400,000 km3)of freshwater is stored in the Earth, most within one-half mile of the surface. But, if you really want to find freshwater, the most is stored in the 7,000,000 mi3 (29,200,000 km3) of water found in glaciers and icecaps, mainly in the polar regions and in Greenland.
