What Causes a Storm to Form and Grow?

A storm is like a giant bubble that forms when warm air rises and cool air falls. Warm air carries moisture, which turns into rain or snow when it cools. The more energy the air has, the bigger the storm becomes. Imagine blowing bubbles with a fan, if you blow harder, the bubbles get bigger and pop louder!
