what is the driving force behind the water cycle?
the clouds
the sun
gravity

Explanation:

The sun's energy causes water to evaporate (turn from liquid to gas). This is the first step in the water cycle. Clouds are part of the water cycle (condensation) but not the driving force. Gravity plays a role (e.g., in precipitation - rain falling down) but the initial and main driving force is the sun's energy for evaporation which starts the cycle.

Answer:

the sun
