Question
Even though each person on the earth uses three buckets of water per day, the amount of water on the Earth still remains almost constant. Which of the following can be a probable reason?
Answer: Option B
:
B
The amount of water on the earth remains almost constant due to the water cycle. The water cycle is a natural continuous process due to which water is circulated from oceans and other water bodies to the atmosphere due to evaporation. The water vapours then undergo condensation and form clouds. Then the water re-enters theland in the form of rain (precipitation), and also flows back to oceans through rivers. This cycle keeps fresh water available for use of all living beings.
