The amount of water that evaporates from earth is
a. less than the amount that falls as precipitation
b. more than the amount that falls as precipitation
c. roughly equal to the amount that falls as precipitation

c

Explanation:

Hi, Evaporation from the oceans is the primary mechanism supporting the surface-to-atmosphere portion of the water cycle.  

On a global scale, the amount of water evaporating is about the same as the amount of water delivered to the Earth as precipitation. This does vary geographically, though. Evaporation is more prevalent over the oceans than precipitation, while over the land, precipitation routinely exceeds evaporation

it's c. (to reduce the greenhouse effect/carbon gasses)

b is the correct answer
