Thunder is the sound of lightning. When lightning strikes, it heats up the air really fast, making it expand and push out like a balloon being blown up, boom! Then the air cools down quickly, creating a wave that travels to your ears, making you hear thunder. It often sounds far away because the sound takes time to reach you.
Examples
- Imagine blowing up a balloon really fast, that’s what happens to the air when lightning strikes.
- It's like someone dropped a big rock into a lake, making ripples that reach your ears later.
- Thunder is the sound of the sky letting out a loud sigh after a lightning strike.
