explain how rain clouds form

Rain clouds form when warm air rises in the atmosphere. The warm air carries water vapor with it, and as it rises it cools and the water vapor condenses into tiny droplets of water. These tiny droplets collect together to form clouds. Think of it like a piece of warm toast. As the toast warms up, tiny little droplets of moisture form on the outside. Those droplets are like the tiny droplets of water in a rain cloud. It takes about one million of these droplets to form a raindrop that is big enough to fall from the cloud. That’s a lot of tiny droplets! Fun Fact: Rain clouds can reach heights of up to 10 miles high in the sky!
