Across
- 4. mostly solid rock flowing under high temperature and pressure
- 5. chain of volcanic landforms that result as magma formed through the melting of subducting plate rises and emerge as volcanoes
- 9. movements of heat within the mantle
- 11. formed when a plate converges with an oceanic plate
- 13. earth's crusts broken into pieces moving relative to each other
- 15. consist mainly of nickel and iron
- 16. where plates move away from each other
- 17. what happens to the denser plate at convergent plate boundaries
- 19. brings rocks close to their melting point for them to be deformed and melted
- 21. a linear depression that is formed when land in between two continental crusts sink
- 22. lighter rock that has cooled down slowly
- 23. heavy dense rock formed from magma which has cooled quickly
Down
- 1. consists mainly of basalt
- 2. molten rock that reaches the earth's surface
- 3. molten rock beneath the earth's crust
- 6. where older crust is destroyed and recycled
- 7. outermost layer of the earth
- 8. formed when 2 oceanic plates move away from each other
- 9. where new crust is formed
- 10. consists mainly of granite
- 12. where plates move towards each other
- 14. consists of the crust and uppermost mantle
- 18. where plates slide past each other
- 20. when denser plate subducts under, dragging the rest of the plate into the mantle
