Which process most directly moves water from the atmosphere to Earth's surface?

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

Answer: (A)

The main idea being tested is how water moves between the atmosphere and Earth’s surface. Precipitation directly moves water from the atmosphere to the surface by rain, snow, sleet, or hail, delivering water downward to land and bodies of water. Condensation forms clouds by turning vapor into liquid droplets in the air, which doesn’t itself add water to the surface. Evaporation is the process of water on the surface turning into vapor and entering the atmosphere, the opposite direction. Transpiration is water released from plants into the air. So precipitation is the direct transfer from air to the surface.
