What is an example of precipitation?

Precipitation refers to any form of water, liquid or solid, that falls from clouds and reaches the ground. Rain is a prime example of precipitation, as it consists of liquid water droplets that form when atmospheric conditions allow for the condensation of water vapor in the clouds. When these droplets become heavy enough, they fall to the earth as rain.

To provide context for the other options, steam is a gas and does not fall to the ground, making it not a form of precipitation. Fog is a collection of tiny water droplets suspended in the air near the ground, but it does not fall as precipitation. Dew is moisture that forms on surfaces when air cools and condenses, but it also does not involve falling from the sky like rainfall does. Thus, rain is distinctly classified as precipitation due to its capability of falling from clouds and directly reaching the surface.
