Which of the following is NOT a process of moisture transfer in the atmosphere?

D is identified as the correct answer because subduction refers to a geological process related to tectonic plates, where one plate moves under another and sinks into the mantle. This process is not relevant to atmospheric moisture transfer, which involves how water changes state and moves within the Earth’s atmosphere.

In contrast, the other processes listed—evaporation, condensation, and precipitation—are fundamental components of the water cycle. Evaporation is the process where liquid water turns into water vapor, thus transferring moisture into the atmosphere. Condensation occurs when water vapor cools and changes back into liquid water, forming clouds or fog. Precipitation is the process of water falling from the atmosphere back to the Earth in the form of rain, snow, sleet, or hail. Together, these processes illustrate the continuous movement and transformation of moisture in the atmosphere, highlighting their essential roles in atmospheric dynamics.
