  1. 2. The process by which new oceanic lithosphere (sea floor) Forms when magma rises to the earth's surface at mid-ocean ridges and solidifies, as older, existing sea floor moves away from the ridge
  2. 4. A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault line
  3. 5. A way of energy that travels through the Earth and earthquakes in all directions
  4. 6. The hypothesis that a single large landmass broke up into smaller landmasses to form the continents, which then drifted to their present locations
  5. 8. The thin and solid outermost layer of Earth above the mantle
  6. 12. The process by which one lithosphere plate moves beneath another plate as a result of technic forces
  7. 17. The boundary between technic plates are colliding
  8. 18. The edge between two or more plates classified as divergent, convergent, or transforms by the movement taking place between the plates
  9. 20. The point in the Earth's surface directly above an earthquake starting point, or focus
  10. 21. The center part of Earth below the mantle
  11. 22. The layer of rock between the Earth's crust and core
Down
  1. 1. A break in a body of rock along which one block moves relative to another
  2. 3. The theory that explains how large pieces of the lithosphere, called plates, move and change shape
  3. 7. The boundary between two tectonic plates that are sliding against each other horizontally
  4. 9. The location within Earth along a fault at which the first motion of an earthquake occurs
  5. 10. The solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle
  6. 11. The process by which Earth's magnetic north pole and magnetic south pole switch positions periodically
  7. 13. Any movement of matter that results from differences in density
  8. 14. The soft layer of the mantle on which the tectonic plates move
  9. 15. The boundary between two technoic plates that are moving away from each other
  10. 16. The strong, lower part of the mantle between the asthenosphere and the outer core
  11. 19. A block of lithosphere that consists of the crust the rigid, outermost part of the mantle
