- 9. What the core is mostly made of
- 11. How scientists study Earth's interior through rock samples
- 14. Where two plates move apart, and new seafloor is created
- 15. Earth's magnetic field is generated by the core's movement
- 19. What happens to pressure as you go deeper into Earth's interior
- 20. A region where one plate sinks beneath another plate
- 21. A piece of Earth's lithosphere that moves and shapes the surface
Down
