Across
- 2. Encourage movement of tectonic plates
- 6. Tectonic hazards that occur within the tectonic plate
- 9. Irregularly broken sections of lithosphere
- 11. The more dense plate is subducted below a less dense plate
- 12. Upwelling of viscous mantle material causing plate move apart
- 13. Rigid outer layer of the earth
Down
- 1. Two plates of similar density create upward thrust
- 3. Solid nickel and iron
- 4. Denser oceanic plates are subducted at cold downwellings
- 5. Semi plastic layer of upper mantle
- 7. Plates move apart due to ridge push
- 8. Mantle material mainly solid
- 10. Plates move side by side along a strike slip boundary
- 14. Tectonic hazards that occur on the edge of tectonic plates
