Across
- 4. solid, center of the Earth; under more pressure and is solid
- 6. waves that only travel through solids
- 8. outermost, physical layer of the crust
- 11. the ring around the s-wave shadow zone
- 12. bodies of "rock" from space that have crashed into Earth
- 14. give scientists actual samples of Earth's upper mantle
- 16. a characteristic, such as rigidity
- 18. compositional layer of Earth below the crust
- 19. solid, thin layer of mantle below the lithosphere
Down
- 1. this part of the center of the Earth is liquid due to high temperatures
- 2. contains dense elements at the center of the Earth
- 3. the chemical makeup of matter
- 5. thin, dense crust underneath the ocean
- 7. waves that travel through solids, liquids, and gases
- 9. circular area of missing s-waves
- 10. waves of energy that travel through rock released by Earthquakes
- 13. thick, less-dense crust under mountains
