Science How Much Water Is There On Earth?

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.

Hmm interesting.. I would have thought there would be more!

lets suck up all the water on earth into a ball and give america a water bomb they wont forget in a hurry

One problem with the graphic is that I don't really get a sense of how high the water orb is from the ground, it doesn't have depth

Well, since it's a sphere, it's diameter is equal to it's height... so 860 miles high.

well, there!!!

That's not a lot of water!

Not a lot of water? I'd say it's just the right amount of water. Like cute raindrop on a flower.

Of course it's going to look small compared to the entire earth. But keep in mind we don't inhabit the whole earth, only a thin thin layer on top of it. 99% of the earth is just magma and whatnot. Even the tallest mountain, which is about 7000 m is about half a percent of the diameter of that water globe.

lol, why you spoiling all the fun??? :(

Fun Fact: Thanks to the water cycle you are all drinking Margaret Thatcher's piss.

Possibly even a T-Rex's piss. Or Abe Lincoln's!

Once we start mastering terraforming and similar things, it would be cool to just have floating oceans in space just for dolphins. In millions of years, they would turn into all-conscious spiritual beings that can bend time and space to their will.

I guess it would look even smaller if it only contained all the fresh/drinkable water on this planet. Alarmingly small.

Hah, just reading this right now, great book

Who said nearly 1.5 Billion cubic kilometres of water isn't a lot?
