16 Thunder Facts for Kids

  1. Thunder is the sound produced by a lightning bolt.
  2. Thunder is produced during a thunderstorm.
  3. Lightning produces a sudden increase in temperature and pressure, which results in the rapid expansion of air around and within the lightning bolt. This expansion creates a sonic shock wave, producing the sound of thunder.
  4. A clap of thunder registers around 120 decibels.
  5. Because sound travels much slower than light you'll always see a flash of lightning before you hear any thunder.
  6. The sound of thunder depends on the type of lightning bolt and how far away you are from it.
  7. The closer you are to a lightning bolt, the more it will sound like a sharp, loud crack, and the farther away you are the more it sounds like a low rumble.
  8. It's impossible to have thunder without a lightning bolt, since thunder is produced from a lightning bolt. However, if you're far enough away from a lightning bolt you'll see the flash, but not hear the thunder.
  9. If you're more than 12 miles (19 kilometers) from a lightning bolt, you most likely won't hear any thunder.
  10. You can actually calculate how far away you are from a lightning bolt by using thunder. When you see a flash of light from lightning, count the number of seconds until you hear the thunder. You can use the timer on your cellular phone or count using the "One-Mississippi, Two-Mississippi, Three-Mississippi," method. Based on how long it takes sound to travel compared to light, every five seconds is one mile. Simply divide the number of seconds you counted by 5, and that's how many miles away the lightning bolt was.
  11. A rare event known as a thundersnow or thundersnow storm is when thunder and lightning are produced during a snow storm.
  12. Since snow is an acoustic suppressor, the sound of thunder in a thundersnow storm can only be heard for a few miles.
  13. The fear of thunder is known as brontophobia. Astraphobia is the fear of thunder and lightning.
  14. Thunder was believed to be caused by clouds colliding together prior to the mid-19th century.
  15. In Greek Mythology, Zeus was the sky and thunder god.
  16. In Norse Mythology, Thor was the god of thunder.
