Unit 7: Plate Tectonics
Across
- 5. outer chemical layer of the Earth
- 7. when a denser tectonic plate moves underneath a less-dense tectonic plate
- 8. landform created from two continental plates colliding
- 9. chemical layers of Earth are separated due to differences in this property
- 10. layer of Earth that is most dense
- 11. thickest chemical layer of the Earth
- 16. type of tectonic boundary that forms when two plates slide past each other
- 18. crust is destroyed at this location as it subducts
- 19. huge pieces of lithosphere that move
- 23. chemical layer of the Earth made of iron and nickel
- 27. method of heat transfer through space, no direct contact
- 29. layer of Earth that is responsible for the Earth's magnetic field
- 31. landform that is present when continental crust diverges or moves apart
- 32. german scientist proposing continental drift
- 33. transform fault in California
- 34. proposed Theory of Seafloor Spreading
- 35. type of crust that is made mostly of basalt, and is more dense
Down
- 1. freshwater reptile fossil that provides evidence for Continental Drift
- 2. type of tectonic boundary that forms with two plates moving apart
- 3. is the solid outer layer that is broken into plates that move
- 4. landform created when two oceanic plates collide
- 5. responsible for the movement of tectonic plates, method of heat transfer through fluids
- 6. landform found at divergent boundary in the Atlantic Ocean
- 12. we refer to polarity as this when the magnetic north pole matches the geographic north pole
- 13. used data from SONAR to create a map of the floor of the Atlantic Ocean
- 14. Volcanic island arc formed from the collision of two oceanic plates
- 15. physical layer of the Earth that flows slowly, allowing the plates to move
- 17. method of heat transfer through direct contact
- 20. grooves formed in bedrock from moving glacial ice
- 21. name of Wegener's supercontinent
- 22. lower part of the mantle
- 24. type of tectonic boundary that forms with two plates moving together
- 25. we refer to polarity as this when the magnetic north pole matches the geographic south pole
- 26. mountains formed from collision of India and Eurasia
- 28. type of crust that is made mostly of granite, and is less dense
- 30. mountain range formed from a collision of oceanic and continental plates
