Question

What is the approximate residence time of atmospheric water? A) 4000 years B) 123123213123 days C) 150 years D) 9 days E) 6000 years

Answer 1

The correct option is d) 9 days

Step-by-step explanation:

First of all the water cycle which is also termed as hydrologic cycle, tells about the continuous movement of water above, below and on the earth's surface.

The residence time of atmospheric water means the amount of time water molecule would spend in a reservoir, which is with in the hydrologic cycle.

Usually the residence time in the atmosphere is 9 days, after evaporation and before it starts condensing and falling to the earth in form of percipitation.
