Since childhood we Knew earth as a water planet and at one point of time we might have stumbled upon this question what if you could take all of the water on Earth and form it into a sphere, or bubble? How big would the bubble be? And this was answered by the U.S. Geological Survey (USGS).

All the water on Earth would fit into a sphere 860 miles (1,385 km) wide. That’s a lot smaller than Earth itself, as the drawing below shows.

It took me by total surprise. And here I was thinking that earth is a watery world. In fact, there’s a lot of water in the large blue sphere depicted above. The largest sphere – representing all water on, in, and above Earth – would be about be about 860 miles (about 1,385 kilometers) in diameter. Whereas the diameter of earth is 8,000 miles (about 12.5 thousand kilometers) i.e. only 12.5% of earths components.

For getting a better idea let me explain it to you the largest blue sphere in the image holds about 332,500,000 cubic miles (or 1,386,000,000 cubic kilometers (km3) water.

{Image 2 comes over here with tag line ( Medium-sized sphere = Earth's liquid fresh water in groundwater, swamp water, rivers, and lakes. Smallest sphere = fresh water in all the lakes and rivers on the planet. Image via Jack Cook/WHOI/USGS).

Seen the smaller sphere just below the large one? It represents Earth’s liquid fresh water in groundwater, swamp water, rivers, and lakes. And if you have noticed a little bit further you would notice a small blue dot that represents fresh water in all the lakes and rivers on the planet. USGS says that most of the water required by people and other earthly life (every day) comes from these surface-water sources.

So what we assume from our naked eye is not afact?

Bottom line: Water is a precious gift given to us by Mother Nature use it wisely.
