Question

What percentage of water is fit for human consumption from the total water available?
A)0.006
B)0.06
C)0.6
D)6

Answer 1

Hint: A very small proportion of all the water on the planet is made up of freshwater. Although water covers almost 70 percent of the earth, just 2.5 percent of it is fresh. The rest is ocean-based and saline.

Complete answer:
Only 0.006% of water is fit for human consumption from the total water available.
There is an abundance of water on the planet, but sadly, only a small amount (about 0.3 percent) can even be used by humans. In the seas, soils, icecaps, and floating in the atmosphere, the remaining 99.7 percent are. Nonetheless, much of the 0.3% that is available is unattainable. Any of the water that human beings use comes from rivers. The observable water bodies are referred to as water from the surface. In fact, most fresh water is discovered underground as soil moisture and in aquifers.

Still lets see options :
0.006% : Only 0.006% of water is fit for human consumption from the total water available thus this option is correct.
0.06% : Only 0.006% of water is fit for human consumption from the total water available thus this option is wrong.
0.6% : Only 0.006% of water is fit for human consumption from the total water available thus this option is wrong too.
6% : Only 0.006% of water is fit for human consumption from the total water available thus this option is wrong too.

Hence, the correct answer is option (A)

Note: Distribution of water on earth is :
1)Ocean water is consists of 97.2% of total water
2)Glaciers and other ice consists of 2.15 % of total water.
3)Groundwater consists of 0.61 % of total water.
4)Freshwater lakes consist of 0.009 % of total water.
5)Inland seas consist of 0.008 % of total water.
