Lightning makes thunder because it heats the air really fast. When lightning strikes, it’s like a giant firecracker in the sky, Boom! The hot air expands and pushes the cold air out of the way, making a sound we call thunder. Sometimes you hear it right after the flash, and sometimes it takes a while because the sound travels slower than light.
Examples
- Thunder sounds like a giant firecracker going off in the sky after lightning strikes.
- You hear thunder because it takes time for the sound to reach you from where the lightning hit.
- Sometimes thunder rolls on and on, like a drum being played far away.
