explain how rain clouds form

Rain clouds form when warm, moist air rises in the atmosphere and cools. As the air rises, it expands and cools, forming tiny water droplets. These droplets then clump together and form clouds. When the water droplets become too heavy to remain suspended in the air, they fall as rain, sleet, hail, or snow. An example of this process would be if you were to heat a pot of water on the stove. As the water warms, it starts to bubble and evaporate. Similarly, as the warm air rises, water droplets form in the air and eventually become too heavy, condensing together to form clouds. Fun Fact: A single cloud can contain up to 4 trillion droplets of water!
