Across
  1. 2. the denser plate sinks below the more buoyant plate
  2. 3. The mountain ranges in the middle of the oceans
  3. 6. the process by wich new oceanic crust forms along a mid-ocean ridge and older oceanic curst moves away from the ridge
  4. 7. the circulation of material caused by differences in tempature and density
  5. 9. Earth's surface is made of rigid slabs of rock, or plates, that move with respect to each other
  6. 10. as slab sinks, it pulls on the rest of the plate
  7. 11. all continents were were once part of a supercontinent
  8. 12. forms where two plates slide past each other
  9. 15. the cold and rigid outermost rock layer
  10. 16. forms where two plates slide past each other
Down
  1. 1. occurs and the magnetic field reverses direction
  2. 4. suggests that continents are in constant motion on the surface of Earth
  3. 5. from where two plates collide
  4. 8. a state in which magnetized objects would reverse direction and orient themselves to point south
  5. 13. rising mantle material at mid-ocean ridges creates the potential for plates to move away from the ridge
  6. 14. a state in which magnetized objects, such as compass needles, will orient themselves to point north
