Across
- 1. theory exploring idea that the 7 continents where once together
- 3. caused Hawaii
- 7. the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances
- 10. formed by convergent boundary
- 12. rotation of the Earth causes the buoyant fluid to rise in curved trajectories, which generate
- 13. created by lateral movements of lithospheric plates
- 14. middle and thickest layer of the earths surface
Down
- 2. lithospheric plates move apart and oceanic crust is created
- 4. Plates underneath the earths crust that shift to move the landscape.
- 5. inside of an objects
- 6. formed by divergent boundaries
- 8. part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments
- 9. occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth's interior.
- 11. mostly iron and nickel; contains radioactive material that break down and produce heat
