Surface-to-Air movement of moisture requires these processes for it to occur.

A) Evaporation into water vapor

B) Transpiration from plants

C) Both A & B

D) None of the above

C) Both A & B

Explanation:

Water exists in three different states, which are the liquid, solid and gaseous state. In the ground and in plants, water usually exist in its liquid form but in order to be taken from surface to air, water must either be lost by evaporation as water vapour from these surfaces, or be lost as vapour in the transpiratation of plants. The combination of these effects is termed evapotranspiration.
