Answer:
The sun
Step-by-step explanation:
The source of energy for the water cycle is the sun. In the solar system, the sun is the ultimate source of energy for the external processes.
The water cycle is powered by the energy from the sun.
- When solar radiation impacts the ocean, water is radiated from its surface into the atmosphere.
- There is a phase change of evaporation that goes in such a procedure.
- Therefore, addition of energy by the sun causes vaporization.
- The water is cooled and precipitation occurs within the clouds as the energy gained is being lost.
