Across
- 2. The materials or elements of which each layer is composed
- 3. This boundary type occurs when 2 plates move apart from eachother
- 6. What happens to an oceanic plate when it converges with a continental plate
- 8. Oceanic plates are mainly comprised of this
- 12. The study of Earth's magnetic polarity
- 15. The uppermost layer of the earth
- 17. Came up with the theory of Continental Drift
- 18. The technology that Marie Tharp used to graph the Atlantic
- 21. The way layers behave due to pressure and heat
- 24. The lithosphere is broken into these
- 27. This force moves the plates
- 29. The most well-known supercontinent
- 31. Lava before it is exposed to the surface
- 33. This occurs at a continental divergent boundary
- 34. A way lava is described
- 35. This occurs when 2 oceanic plates pull away from eachother
- 36. This is the name for when the Earth's magnetic field flips
- 37. This layer is broken into the tectonic plates
- 38. The type of boundary that occurs when 2 tectonic plates move past eachother
Down
- 1. This iron-rich mineral helps show the Earth's polarity
- 4. Stiff and firm
- 5. Marie Tharp assisted in the creation of this theory
- 7. This crust is made of basalt
- 9. The 2nd most inner layer of the Earth
- 10. This occurs at a convergent plate boundary near a subduction zone
- 11. Earthquakes give these waves off
- 13. Alfred Wegener came up with this this theory
- 14. Semi-Molten layer of the upper mantle
- 16. Graphed the northern Atlantic by hand
- 19. The largest layer of the Earth
- 20. This event is when sudden forces are released at a boundary and California is known for it
- 22. This crust is much deeper than the other
- 23. The innermost layer of the Earth
- 25. The type of lava that comes out at a Mid-Ocean Ridge
- 26. This boundary type occurs when 2 plates move towards eachother
- 28. The Earth is surrounded by this and it makes compasses work
- 30. Continental Plates are mainly comprised of this
- 32. What happens at mid-ocean ridges
