Thunderstorm Formation and Characteristics

Giuliana, a fifth grader, asks how thunderstorms are created. The teacher explains that thunderstorms require warmth, moisture, rising unstable air, and a lift like a cold front. A demonstration using water shows how warm air rises, cools, condenses, and eventually forms thunderstorms with rain and lightning.
