Plate Tectonics
Across
- 3. a tectonic plate covering most of North America
- 6. made from transform plate boundaries
- 8. a tectonic plate containing the continent of Antarctica
- 9. the crust and the uppermost mantle into a rigid layer
- 11. Forms when two plates separate
- 12. forms where 2 plates collide
- 14. the denser plate sinks below the other plate
- 16. made from convergent plate boundaries
- 17. forms where two plates slide past each other
- 19. Earths surface, made of rigid slabs of rocks or plates.
Down
- 1. a tectonic plate which includes most of the continent of Eurasia
- 2. plastic layer in the mantle
- 4. a major tectonic plate in the eastern and, largely, southern hemispheres.
- 5. made of lithosphere and asthenosphere
- 7. formed by divergent plate boundaries
- 10. an oceanic tectonic plate that lies beneath the Pacific Ocean.
- 13. a major tectonic plate which includes the continent of South America
- 15. a major tectonic plate straddling the Equator as well as the prime meridian.
- 18. As a slab sinks, it pulls on the rest of the plate with a force
- 20. The least dense layer
