Water Cycle

As a part of the water cycle, water from Earth's surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• Evaporation, Condensation, Precipitation

• Precipitation, Condensation, Evaporation

• Condensation, Evaporation, Precipitation

• Evaporation, Precipitation, Condensation

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.
