Answer: evaporation of water is equal to precipitation of water
Step-by-step explanation:
An hydrological cycle or water cycle is the cyclic process in which the water circulates between different spheres of the earth in solid, liquid and gaseous forms. It circulates in earth's ocean or any other water body, then the vapors reach upto the atmosphere due to evaporation, where these vapors condense and precipitate into rain or snow, again it becomes part of the water body.
On the basis of the above explanation, evaporation of water is equal to precipitation of water is the correct option for the maintenance of the balance of the hydrological cycle on earth.
