Question

Describe how an increase in humidity can affect the water cycle

Answer 1

An increase of humidity can affect the water cycle because since humidity is the amount of water vapor in the air it means it is more likely to precipitate (rain)

Answer 2

An increase in humidity can strengthen the water cycle, because humidity is essentially boosted evaporation. When you have evaporation, that comes automatically with condensation and precipitation, so rain and cloud cover increases.
