Earth's Life
Across
- 2. process where one plate sinks beneath the other
- 5. a deeper depression in the ground
- 8. type of boundary that move towards each other
- 13. fastest type of seismic waves
- 16. aside from earthquake,divergent boundary will produce
- 17. FORMED WHEN TWO CONTINENTAL PLATES COLLIDE
- 23. the shockwaves of released energy that shakes the Earth
- 26. type of boundary that slide past each other
- 27. boundary between two or more plates
- 31. proponent of The Continental Drift Theory
- 32. the outer part of the Earth
- 35. only p-waves can travel along the,
- 36. occurs in all types of boundaries
- 38. a supercontinent that broke apart and the continents drifted to their present positions.
- 39. continental-oceanic convergence forms,
- 40. used to determine the distance of the epicenter from each station
Down
- 1. layer of the Earth that consists of crust and upper mantle
- 3. seismic wave that travels through the Earth rather than across its surface.
- 4. type of boundary that moves away from each other
- 6. crust under continents and other land masses
- 7. type of convergence where continental and oceanic plates collide
- 9. underwater mountain range that is formed by plate tectonics
- 10. is the molten or semi-molten natural material from which all igneous rocks are formed
- 11. a concentration of heat in the mantle capable of creating magma
- 12. states that the Eartgh's surface or the lithosphere is divided into plates that constantly move
- 14. middle layer of the Earth
- 15. landmass existed 200 million years ago
- 18. composed of land,water and air
- 19. slowest kind of seismic waves
- 20. part of the upper mantle that is made up of solid rocks that are able to flow.
- 21. crust that is under the world's oceans
- 22. the inside layer of the Earth
- 24. a chain of volcanoes that is formed parallel to a trench
- 25. type of seismic wave that arrives second
- 28. type of convergence where two thick continental plates collide
- 29. type of convergence where convergent boundary occurs between two oceanic plates
- 30. a geological process that forms new areas of oceanic crust
- 33. the movement of the plates
- 34. Greek word for "earthqake"
- 37. surface seismic waves that has "shearing nature"
