plate tectonics
Across
- 2. outer most layer of earth
- 4. tectonics/ theory that says the earth's crust and upper mantle are broken into dections
- 6. core/ solid core composed of dense iron and nickel
- 7. Adreas Fault/example of a transform fault boundry
- 8. boundry/where 2 plates are moving towards each other
- 9. mountains/example of a boundry where continental crust collided
- 11. crust and upper mantle
- 13. drift/ theory that the continents move
- 17. largest layer inside earth
- 18. core/ liquid core composed of iron and nickel
Down
- 1. trench/ deepest spot in the ocean example of converging oceanic plates
- 3. zone/ area where denser converging plate decends or sinks under a less dense converging plate
- 5. boundry/boundry b/w 2 plates that are separating
- 10. plastic layer below the lithosphere
- 12. super continent that existed 200 million yrs ago
- 14. boundry/boundry where 2 plates are moving or sliding next to each other
- 15. wegener/ scientist who thought that the continents were one super continent
- 16. large sections of earth's crust and upper mantle, lithosphere
