Across
- 4. Formed by ocean to continent convergent boundaries
- 8. Plates move on top of this layer
- 10. Formed by continent to continent convergent boundries
- 11. Tectonic plates are made from this layer
- 14. Hot rock rises, cool rock sinks
- 15. Boundary where tectonic plates slide past each other
- 16. Molten rock from a volcano
- 17. When one plate sinks under another plate
- 19. Most common type of divergent boundary
Down
- 1. Theory that the Earth's crust is divided in sections
- 2. The rate of movement in plates
- 3. Boundary where tectonic plate collide
- 5. Plate sinks and is pulled down by gravity
- 6. Boundary where tectonic plates seperate
- 7. Where the San Andreas Fault is located
- 9. Formed by transform boundaries
- 12. Mid ocean ridge forces older crust to move
- 13. Helps to track plate movement
- 18. A place where tectonic plates touch
