Across
- 3. the process that the oceanic crust sinks beneath the deep sea trench
- 7. the core that surrounds the inner core and is made of iron
- 10. The outermost layer of the earth (located in the lithosphere)
- 11. when two plates slide past each other
- 14. The different parts that form the inside and outside of the earth
- 15. consist of two layers (crust and upper mantle)
- 16. the theory that the plates have moved over time
- 17. the formation of crust
- 18. the part of earths crust that forms new seafloor
- 20. The innermost layer that consist of nickle and iron
Down
- 1. a layer of earth that is located between the crust and the outer crust
- 2. the layer that is located inside the lithosphere and allows convection currents to move the plates
- 4. the layer of earth that's located below the crust (in the lithosphere)
- 5. plates that make up the earths crust (comes in different shapes and sizes)
- 6. the thick layer of earths crust that forms large amounts of earth's landmasses
- 8. forms a divergent boundary on earths surface
- 9. the layer of gas that surround the earth
- 12. Plate boundaries that force two plates to separate
- 13. a break in the earths crust
- 19. When two or more plates come together and collide
