All of Earth's Water in a Single Sphere
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.

I've seen this, or similar pic, before and I just can't believe this is
accurate...somebody forgot to carry a 1 or misplaced a decimal or something

Regarding the accuracy of this... I know it's hard to conceive but remember,
while the Pacific ocean is 10-15,000 km across in places the average depth is
only 3.8km (2.35 miles). That makes it > 2600 times wider than it is deep.
They are pretty thin layers. Let me put that into perspective for you.
Tin foil is 0.2mm thick. If you cut a piece of tin foil 520mm (20.5 inches)
long, then you have about the same thickness to width ratio as the average
dimensions of the Pacific ocean.

Spring water is ground water so yes it is included in the estimate.
They used old 486SX CPUs and Windows calculator to do the math.

Don't confuse them with facts Onyama. Just tell them beer is 90% water and they
forgot to include Milwaukee.
