Scientists use waves to peek inside the Earth. Just like you can tell what's in a bag by how it feels when you shake it, scientists send vibrations through the ground and see how they bounce back. This helps them imagine what the inside of the Earth looks like, kind of like solving a mystery with sound.
Examples
- A scientist drops a ball into a pool to see how it moves, just like they use seismic waves to map inside the Earth.
- You can tell if your friend is holding something heavy by how quickly you feel their hand move, scientists do similar things with earthquakes.
- When you hit a bell, sound travels through air and metal differently, this helps scientists guess what's inside the Earth.
