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