How is the atmosphere important to the water cycle?

Answer:The atmosphere is full of water

.

Explanation:

Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents

Evaporation, condensation, precipitation, are all steps in the water cycle.

None of these can happen without an atmosphere = ==> without atmosphere, there simply IS no water cycle.
