Which term describes the movement of water from the atmosphere to the ground, including rain, snow, sleet and hail?

• A. Transpiration
• B. Infiltration
• C. Groundwater flow
• D. Precipitation

Answer: (D)

This question tests understanding of the term for water moving from the atmosphere to the ground as rain, snow, sleet or hail. That process is precipitation, the part of the water cycle where atmospheric moisture falls to the surface in various forms. It happens when water vapour cools and condenses into droplets large enough to fall under gravity, producing rain, snow, sleet, or hail. Transpiration describes water loss from plants, not the arrival of moisture from the air to the ground. Infiltration is the subsequent entry of surface water into the soil. Groundwater flow is the movement of water through rocks underground. So precipitation is the correct description of the transfer from air to the surface in all those forms.
