Plate tectonics
Across
- 2. The less dense plate slides under the more dense plate creating a subduction zone
- 6. Boundary between two plates that are moving apart or rifting
- 7. Boundary between two plates that are sliding past each other
- 12. The plastic layer below the lithosphere
- 15. Causes sea floor spreading
- 17. Where the less dense plate slides under the more dense plate
- 18. The earths crust and upper mantle are broken into section called plates
- 19. Extremely hot liquid and semi-liquid rock located under earths surface
- 20. The crust and part of the upper mantle
Down
- 1. Divergent, convergent, transform boundary
- 3. boundaries between two plates that are colliding
- 4. hot magma in the Earth moves toward the surface, cools, then sinks again
- 5. Plates below the continents
- 8. Occurs at subduction zones
- 9. fault
- 10. Collision zones
- 11. Happens when two blocks of the earth suddenly slip past one another
- 13. Moving past each other
- 14. Plates below the ocean
- 16. Hitting each other
