During which process does water vapor return to earth?

• A. Transpiration
• B. Evaporation
• C. Condensation
• D. Rainfall

Answer: (D)

The process through which water vapor returns to Earth is best described as rainfall. This is part of the water cycle, where water vapor in the atmosphere condenses into droplets that coalesce to form clouds. When the droplets become heavy enough, they fall back to the Earth's surface as precipitation, which includes rain, snow, sleet, or hail. Rainfall plays a critical role in replenishing freshwater supplies, supporting ecosystems, and maintaining the overall balance of the water cycle. It is the final step in the journey of water vapor moving from the atmosphere back to the ground, making it an essential component for both natural and human-made environments. Other processes mentioned, like transpiration, evaporation, and condensation, are parts of the broader water cycle but do not directly represent the return of water vapor to the earth. Transpiration involves water vapor release from plants, evaporation is the process of liquid water turning into vapor, and condensation refers to the transformation of vapor back into liquid, which precedes rainfall but does not encompass the act of water returning to the surface itself.
