Plate tectonics
Across
- 4. an opening in Earth’s crust from which lava, gas, and ash erupt
- 7. a layer of the upper mantle in which rocks can deform like plastic
- 9. boundary a boundary between plates that are moving toward each other
- 11. tectonics the movement of plates that make up Earth’s surface
- 12. the layer of Earth between the crust and the core
- 13. the rocky outer layer of Earth
Down
- 1. zone an area in a convergent boundary where two continents are colliding
- 2. zone a convergent boundary where one plate is sliding beneath another
- 3. boundary a boundary between plates that are moving away from each other
- 5. the rigid upper layer of the Earth
- 6. shaking and vibration of Earth’s surface
- 8. a boundary between plates that are sliding past one another
- 10. a rigid section of Earth’s crust that moves very slowly
