Across
- 3. hypothetical land area believed to have once connected nearly all of the earth's landmasses together
- 5. The solid outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
- 6. The strong lower part of the mantle between the asthenosphere and the outer core.
- 7. Stress that occurs when forces act to squeeze an object
- 11. Floor Spreading/ The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies
- 12. Drift/ The hypothesis that states that the continents once formed a single landmass ,broke up, and drifted to thier present locations
- 14. Tectonics/ The theory that explains how the Earths tectonic plates move and change shape
- 15. Boundary between Tectonic Plates that slide past each other horizontally
- 16. Stress that occurs when force act to stretch an object
- 17. The central part of the Earth below the mantle
- 19. Boundary between 2 Tectonic Plates that are moving away from each other
Down
- 1. A break in a body or rock along which one block slides relative to another
- 2. Lift/ The rising of regions of the Earths crust, to higher elevations
- 4. A soft layer of the mantle on which tectonic plates move
- 8. The sinking of regions on the Earths crust, to lower elevations
- 9. Plates/ A block of lithosphere that consists of the crust and rigid, most outer part of the mantle
- 10. The layer of rock between the Earths crust and core
- 12. Boundary formed by collision of 2 Lithospheric Plates
- 13. The bending of rock layers due to stress
- 18. The thin and solid outermost layer of the Earth above the core
