What Is Lightning?


Lightning...




Lightning is an atmospheric discharge of electricity that accompanied with thunder. It usually occurs during thunderstorms and sometime during volcanic eruptions. When atmospheric discharge the electricity, the leader of bolt of lightning can travel at speed 60000 m/s and its temperature can reach until 30000 oC. Based on the statistic, approximately 16 million lightning storms occur in the world every years.

How Lightning Occurs?


Lightning occur due to the great difference of charge between two regions. When the difference of charge achieve a certain point, air between two regions become ionize or breaks down and cause the lightning to occurs. When this phenomena happens, the larger amount of energy is used and converted into light, heats and sound. That is why during lightning, it sound like thunder.
