What is the process by which water vapor becomes liquid, often forming clouds, followed by precipitation?

Explanation:
The main idea here is how water in the air changes from a gas to a liquid and then falls as rain or other forms of precipitation. Water vapor cools and condenses into tiny liquid droplets. These droplets come together to form clouds. When droplets grow too large to be held up by air, gravity pulls them down as precipitation, such as rain, snow, or hail. That sequence—condensation turning vapor into liquid, cloud formation, and then precipitation—is exactly what’s described. Other options don’t fit because evaporation is liquid turning into gas, not gas turning into liquid; sublimation is solid turning directly into gas; and runoff describes water moving over land rather than a change in state.
