Across
- 1. One piece of evidence for continental drift
- 4. Where tectonic plates meet and interact
- 6. Side effect / result of divergent boundary
- 7. Happens to the sea floor; makes new crust
- 11. Type of current where hot, less dense items rise and cooler, more dense items sink
- 12. Composed of the crust and upper mantle
- 13. The mantle is full of this molten rock
- 14. Side effect / result of convergent boundary
- 15. Scientist in 1912 that proposed Continental Drift
- 17. Large pieces of the crust that fit together like puzzle pieces
- 18. Geologist in 1960s who came up with Sea Floor Spreading
Down
- 2. When a less dense piece of crust plunges below a more dense piece of crust
- 3. Coolest layer with the least pressure
- 5. State of the rock in the lithosphere
- 7. The speed at which tectonic movement happens
- 8. Side effect / result of a transform boundary
- 9. The once massive super continent
- 10. Hottest layer with the most pressure
- 13. State of the rock in the mantle
- 16. Largest layer of Earth where convection currents happen
