Across
  1. 5. the outermost layer of the earth
  2. 7. the largest tectonic plate on earth
  3. 8. this is the second layer of the Earth that makes 60% of the planet's mass.
  4. 11. it is composed of the upper mantle and crust
  5. 12. giant pieces of the earth's crust
  6. 13. elements found in the inner and outer core
  7. 14. this is formed when subduction happens
  8. 16. it is the study of the earth
  9. 18. this is the process where the plates move below another plate
  10. 19. plate boundaries that slide past each other
  11. 20. these are plate boundaries that moves away from each other
  12. 21. plates that are found on land
  13. 22. the solid core
  14. 23. it is the movement of the upper mantle
Down
  1. 1. the supercontinent
  2. 2. These is the plates that are found under the sea
  3. 3. the part of the upper mantle where magma flows
  4. 4. this is the device that measures the waves of the ground
  5. 6. the liquid core
  6. 9. plate boundary that moves towards each other
  7. 10. states that a long time ago there is one supercontinent on earth
  8. 12. the ocean around the supercontinent
  9. 15. these are formed above convergent boundaries
  10. 17. the German Geologist who proposed the Continental Drift Theory
