This is a visual comparison of all the water on earth compared to the actual size of earth, if all the water where held in a sphere. As you can see, it doesn't look like very much. Weird, I could have sworn I learned in school that the oceans went all the way through earth's core. "What the f*** what kind of school did you go to?" Home.
The picture...shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. You're probably thinking I missed a decimal point when running my calculator since surely all the water on, in, and above the Earth would fill a ball a lot larger than that "tiny" blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas. But, no, this diagram is indeed correct.
About 70 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and...even in you and your dog. Still, all that water would fit into that "tiny" ball. The ball is actually much larger than it looks like on your computer monitor or printed page because we're talking about volume, a 3-dimensional shape, but trying to show it on a flat, 2-dimensional screen or piece of paper. That tiny water bubble has a diameter of about 860 miles, meaning the height (towards your vision) would be 860 miles high, too! That is a lot of water.
Wow, with so little looking water I almost feel bad having a pool. Just kidding, I don't have a pool. My bedroom does flood when it rains though. It makes the carpet smell ooky!
Thanks to beebs, who actually stumbled upon this graphic looking for an accurate moon to moon-cheese comparison.
