Across
- 3. waves are taken in by the medium they enter and do not get through
- 6. S waves are known as
- 8. made of the middle mantle
- 10. S waves travel in this pattern
- 12. P waves are known as
- 14. crust that is thinner but more dense
- 15. a process in the mantle that drives the movement of the plates
- 17. crust that is thicker but less dense
- 19. place on the surface of the Earth above the focus of the earthquake
- 20. happens near a subduction zone
- 21. cannot travel through liquid
- 22. happens at a divergent boundary
Down
- 1. happens at a convergent boundary
- 2. happens at a transform boundary
- 4. can travel through liquid
- 5. when two plates slip alongside each other and cause an earthquake
- 7. P waves travel in this pattern
- 9. happens to waves when they travel through different densities
- 11. a place where certain waves cannot travel
- 13. happens when plates converge and one slides beneath the other
- 16. made of the crust and upper mantle
- 18. waves produced by an earthquake
