What is lightning?

Lightning is an atmospheric discharge of electricity, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of 60,000 m/s, and bolts of lightning can reach temperatures approaching 30,000°C (54,000°F), hot enough to fuse soil or sand into glass channels. There are over 16 million lightning storms every year.
