Check understanding

- Explain that the crust is thin compared to the other layers
- State that Earth's interior is extremely hot — hot enough to melt rock
“If your child cracks open a hard-boiled egg, can they compare it to Earth and name the three layers — crust on the outside, mantle in the middle, and core at the centre?”
