Interesting Facts About Lightning


Lightning

1. Every year, the Earth experiences an average of 25 million lightning strikes during some 100,000 thunderstorms. That’s more than a hundred lightning bolts per second.

2. Lightning bolts travel at speeds of up to 60,000 miles per second.

3. The temperature of a typical lightning bolt can reach 30,000 °C – that is about 5 times greater than the temperature of the surface of the Sun.

4. The energy contained in a single lightning strike can power a 100 Watt light bulb for 90 days.

5. Trees sometimes can take direct hits from lightning and not get burnt – the electricity passes over their wet surface and goes straight into the ground.
