Plate Tectonics
Across
- 2. layer of rock between the crust and core
- 5. hypothesis that states that the continents once formed a single land mass
- 7. soft layer of the mantle on which the tectonic plates move
- 9. set of deep cracks that form between two tectonic plates
- 12. where sea floor spreading takes place
- 16. boundary formed by collision of two lithospheric plates
- 18. theory that explains how large pieces of the earth's outermost layer
- 21. boundary between two tectonic plates
- 22. rim of volcano
Down
- 1. thin and solid outermost layer of the earth above the mantle
- 2. strong lower part of the mantle between the asthenosphere and outer core
- 3. fault when rocks are pulled apart because of tension
- 4. earth's magnetic poles change places
- 6. stress occurs when forces act to stretch an object
- 8. bending of rock layers due to stress
- 10. solid outer layer of the earth that consists of the crust and the rigid upper part of the mantle
- 11. block of lithosphere that consists of the crust and rigid outermost part of the mantle
- 13. fault when rocks are pushed together by compression
- 14. central part of the earth below the mantle
- 15. rising regions of earth's crust to higher elevation
- 17. boundary between two tectonic plates sliding past each other horizontally
- 19. stress occurs when forces act to squeeze an object
- 20. sinking of regions of earth's crust to lower elevation
- 23. break in a body of rock where one rock slides relative to another
