Across
  1. 3. Very long mountain ranges in the middle of the oceans
  2. 10. The process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge
  3. 12. liquid portion of the core
  4. 13. Dense oceanic plate slides under Less dense continental plate
  5. 16. where rocks first move along the fault, at a location inside Earth
  6. 17. scale that measures the total amount of energy released by the earthquake
  7. 23. boundaries that Forms where two tectonic plates slide past each other
  8. 25. move at right angles relative to the direction the wave travels, slower, does NOT travel through liquids
  9. 26. solid portion of the core
  10. 27. a rigid layer including the crust and the uppermost mantle
  11. 29. hypothesis that the continents are in constant motion on the Earth’s surface
  12. 30. outer part of the magnetic field that affects the charged particles
  13. 31. the thick middle layer in the solid part of Earth
  14. 32. Supercontinent that has broken apart over time
  15. 33. an elastic wave in the earth produced by an earthquake or other means
Down
  1. 1. vibrations in the ground that result from movement along breaks in Earth’s lithosphere, called faults
  2. 2. plastic layer within the mantle
  3. 4. boundaries that Form where two tectonic plates separate
  4. 5. dense metallic center of Earth
  5. 6. push-pull motion similar to a coiled spring,fastest
  6. 7. this is the force that moves the tectonic plates
  7. 8. rock that makes up the ocean floor
  8. 9. move up and down in a rolling motion, causes most damage, slowest
  9. 11. basalt is rich in this mineral
  10. 14. Neither plate is subducted, the less dense plate folds and deforms and mountains are formed
  11. 15. When the denser plate sinks below the more buoyant plate
  12. 18. the location on Earth’s surface directly above the earthquake’s focus
  13. 19. forms near the edge of a continent at an ocean to continent boundary
  14. 20. Scientist that researched whether all the continents had always been in the same place on Earth
  15. 21. boundaries that form Where two plates collide
  16. 22. brittle, rocky outer layer
  17. 24. a break in Earth’s lithosphere where one block of rock moves toward, away from, or past another
  18. 28. Earth’s surface is made of rigid slabs of rock, or plates, that move with respect to each other
