Earths interior and processes
Across
- 4. Layer of rock that forms Earths outer surface
- 5. Layer of molten iron and nickel that surrounds the inner core of earth
- 7. Plate boundary where two plates move away from each other
- 8. Fault where hanging wall slides upwards
- 10. A type of fault where the hanging wall slides downwards
- 13. in the earths mantle caused by density changes
- 16. Theory that all the continents were once joined together
- 18. Hot solid material between earths crust and core
- 19. Molten material adds new oceanic crust
- 22. Rigid layer of upper most part of the mantle and crust
Down
- 1. Stress that squeezes the rock until it folds or breaks
- 2. Stress that stretches the rock so that it becomes thinner in the middle
- 3. Plate boundary where plates move toward each other
- 6. Break or crack in earths lithosphere that rocks move along
- 9. Theory that pieces of earths lithosphere are in constant motion
- 11. Dense sphere of solid iron and nickel
- 12. Plate boundary where two plates move past each other
- 14. Single landmass that broke apart 225 million years ago
- 15. Type of fault where rocks move past each other side ways
- 17. Block of rock that forms upper half of a fault
- 20. Oceanic crust sinks beneath a deep oceanic trench and back into th mantle
- 21. Block of rock that forms the lower half of a fault
