Think of Earth like a giant layered cake. We can't eat it to see inside, but we use vibrations, like shaking the cake to see how each layer moves. These vibrations come from earthquakes, and by watching how they travel through Earth, scientists figure out what's inside. It’s like listening to echoes in a cave to know where you are.
Examples
- A shake in one part of the world can tell scientists about layers deep below.
- It's like feeling how a cake moves after you drop it from a height.
- The way vibrations change helps us find out what's hiding inside Earth.
