  • In the atmosphere, water exists as a gas (water vapor from evaporation), as a liquid (droplets of rain and liquid water that coats solid particles), and as a solid (snow and ice).
  • The water in the atmosphere makes up only a very small percentage of the total water on Earth i.e 0.001%.
  • Hence Out of the total at any time, water present in the atmosphere is 0.001%.
  • So, the correct answer is '0.001%'.
