How many gallons of water are on Earth?

Answer 1

The total water supply of the world is 326 million cubic miles (a cubic mile is an imaginary cube (a square box) measuring one mile on each side). A cubic mile of water equals more than one trillion gallons.

About 3,100 cubic miles 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 cubic miles of precipitation each day.

Each day, 280 cubic miles 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.

Of the freshwater on Earth, much more is stored in the ground than is available in lakes and rivers. More than 2,000,000 cubic miles of fresh water is stored in the Earth, most within one-half mile of the surface. Contrast that with the 60,000 cubic miles of water stored as fresh water in lakes, inland seas, and rivers. But, if you really want to find fresh water, the most is stored in the 7,000,000 cubic miles of water found in glaciers and icecaps, mainly in the polar regions and in Greenland.Where is Earth's water located?
For a detailed explanation of where Earth's water is, look at the data table below. Notice how of the world's total water supply of about 326 million mi3 of water, over 96 percent is saline. And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Thus, surface-water sources (such as rivers) only constitute about 300 mi3 (1,250 km3) (about 1/10,000 th of one percent of total water), yet rivers are the source of most of the water people use.

Answer 3

That's not true, norwood. What about icy comets? And do we measure ice caps as gallons or cubic metres? Gallons are strictly liquid measures.

The actual answer took me 48 seconds to find using a search engine. Maybe you should use your fingers to type after putting your brain in gear before asking such a dumb question?

Answer 4

no one can answer this question. not all water on the planet has been found and the amount increases each day. a result of burning natural gas. a molecule of methane (natural gas) produces 1 molecule of co2 and two molecules of h2o.

Answer 5

75% of earth is water

Answer 6

all of them
