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!
Thunderstorms are created by updrafts of warm, humid air. When that rising air cools off at the higher altitudes and the humidity condenses into rainfall or hail, it creates downdrafts and outflows of cool, dry air that race ahead of the storm and the rainfall.
