Think About It: What would happen if the Sun is removed from the water cycle?

• The water cycle would not include precipitation but would continue with groundwater flow.

• The water cycle would no longer occur because the Sun provides the energy for evaporation and transpiration.

• The water cycle would no longer occur because the Sun provides energy for the formation of clouds.

• The water cycle would not include evaporation and transpiration but would continue with condensation.
