What Causes a Thunderstorm to Form?

Thunderstorms happen when warm air rises and cool air falls, creating a big mix-up in the sky. Warm air is like a balloon, it floats up because it's lighter than cold air. When this warm air goes up, it cools down, making clouds form. Inside these clouds, tiny bits of ice and water crash into each other, causing electricity, that’s how lightning happens! The loud boom you hear is thunder, made by the lightning heating up the air around it.
