Thunder is the sound we hear after seeing lightning. When lightning hits, it heats up the air so fast that the air around it expands and creates a big boom, like when you pop a balloon really quickly! The farther away the lightning is, the longer it takes for the sound to reach us, which is why thunder sometimes seems to rumble.
Examples
- When you hear a big boom after seeing a flash in the sky, that's thunder.
- Thunder feels louder when it’s closer to you, like when it seems to shake your chest.
