Watery Planet? No, Earth Contains Very Less Amount of Water

You have learnt in your lower classes that earth is a watery planet. But now studies show it could be wrong. New research from the US Geological Survey claims that all of the water on earth is less than a third the size of the moon. That means absolutely very less amount of water. 

Based on this study, if you take all of the water on earth including salt water, water in the ice caps, the atmospheric water and the fresh water, it would make a ball of 860 miles (1,385 km) in diameter. This is comparable to the wide edge-to-edge distance between Salt Lake City to Topeka, Kansas.

Aren’t you shocked? Actually most of earth’s available fresh water is underground even if you consider the reservoirs, lakes and rivers which comes around 2 million cubic miles (8.4 million cubic km).

The majority of it is in the ice sheets in Antarctica and Greenland which are over than 7 million cubic miles (29.2 cubic km).

While considering only the fresh water on earth, which is 2.5% of the total amount, you get a much smaller sphere that is less than 100 miles (160 km) across.

But you don’t have to panic, because the total amount of water on Earth is still quite impressive with over 332.5 million cubic miles (1,386 cubic km).
