Thunder is caused by the rapid expansion and contraction of the air surrounding a lighting bolt. On average, a lightning bolt is about 5 times hotter than the surface of the sun or about 50,000Â°F!
Every thunderstorm produces lightning, which kills more people than tornadoes each year. Thunderstorms also cause heavy rain, flash flooding, hail, strong winds and tornadoes. When warm and cold air masses meet, a thunderstorm can grow. In this activity, you will learn about convection and how air moves.
