Wonderful piece of info from the U.S. Geological Survey

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..."

Mindblowing...Don't you just love maths!!

dont believe it, would be bigger i reckon

I don't believe it too... looks more like propaganda to fool people that there isn't that much water in the world and to make water expensive...

The image is based off the USGS study which states that despite the fact 70 percent of the world's surface is water, all the water in the world would form a sphere stretching only 860 miles (1,385 kilometers). The USGS states that this equals the distance from Salt Lake City, Utah to Topeka, Kansas. For our European readers this is almost exactly the distance between London and Zagreb, Croatia.

Now for the truly mind blowing fact. USGS estimates that freshwater comprises only 2.5 percent of all water, so I calculate that all the world's fresh water would form a sphere stretching only 21.5 miles (34.6 kilometers)! That is shorter than some people's commute.

BUT:

A sphere with a diameter of 21.5 miles would have a volume of 5204 cubic miles. Wikipedia puts the volume of the great lakes at 5439 cubic miles, so something appears a little off there.

You can't drink the sea!!

This drawing shows various blue spheres representing relative amounts of Earth's water in comparison to the size of the Earth. Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth. This image attempts to show three dimensions, so each sphere represents "volume." The volume of the largest sphere, representing all water on, in, and above the Earth, would be about 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)), and be about 860 miles (about 1,385 kilometers) in diameter.

The smaller sphere over Kentucky represents Earth's liquid fresh water in groundwater, swamp water, rivers, and lakes. The volume of this sphere would be about 2,551,000 mi3 (10,633,450 km3) and form a sphere about 169.5 miles (272.8 kilometers) in diameter. Yes, all of this water is fresh water, which we all need every day, but much of it is deep in the ground, unavailable to humans.

Do you notice that "tiny" bubble over Atlanta, Georgia? That one represents fresh water in all the lakes and rivers on the planet, and most of the water people and life of earth need every day comes from these surface-water sources. The volume of this sphere is about 22,339 mi3 (93,113 km3). The diameter of this sphere is about 34.9 miles (56.2 kilometers). Yes, Lake Michigan looks way bigger than this sphere, but you have to try to imagine a bubble almost 35 miles high—whereas the average depth of Lake Michigan is less than 300 feet (91 meters).

looks like it might be true!

Don't believe it.
Must be way more.
(Maths is a biatch and cause of that i don't bang her.)

I definitely don't believe it . Half the water in the fkn Amazonian Rainforest has been pissing down on me all year .

Ha!Ha!Ha! same here!

And this is how much fresh water there is, compared to Earth and the total amount of water:

It looks like this is the estimation given, by every one!
