Thunder is what you hear when lightning happens. When lightning strikes, it heats up the air really fast, like a giant firecracker going off in the sky! This hot air expands and makes a boom that we can hear. Sometimes the boom sounds far away because sound travels through the air slowly, just like how your voice takes time to reach someone across a room.
Examples
- Thunder sounds like a big explosion because it’s like lightning causing the air to pop.
- You can hear thunder even when you’re on the other side of the lake, that’s how far sound travels!
- Sometimes, thunder can be so loud it feels like the sky is shaking.
