  6. 13. device that measures vibrations in the Earth and converts them into electric signals
  7. 15. series of vibrations in the Earth caused by plate tectonics
  8. 20. type of boundary where two plates slide past each other
  9. 21. vent in the Earth's crust through which magma, steam and ash can be expelled
  10. 23. plate boundary where two plates move away from each other
  11. 25. hot liquid layer of the Earth made of iron and nickel

Down
  1. 1. conduction, convection and radiation
  2. 2. a long narrow land mass between two divergent plates
  3. 3. liquid part of upper mantle below the lithosphere
  4. 5. area of science that studies the movement and interaction of the Earth's plates
  5. 7. heat transfer by the movement of a liquid or a gas
  6. 8. portion of the Earth made up mostly of a very thick molten liquid
  7. 10. process that occurs at mid-ocean ridges where rising magma creates new ocean crust
  8. 11. motion created with the hand and wrist to say hello or goodbye
  9. 14. energy wave that travels through the Earth caused by motion
  10. 16. used by Dr.Wegener to help support his hypothesis

  12. 18. type of rock produced under extreme heat by volcanoes and magma
  13. 19. molten material beneath the Earth's crust that can create igneous rock
  14. 22. area on the ocean floor where seafloor spreading takes place
  15. 24. transfer of heat through empty space
  16. 26. rocks formed when sediment is deposited and becomes tightly compacted
  17. 27. elevation of the Earth's surface created by divergent or convergent plates
  18. 29. the thin outermost layer of the Earth
  19. 33. depression in the ground caused by the collapse of the surface from moving water
