Across
  1. 3. ridge- a range of underwater volcanoes that wrap around the globe
  2. 4. the force applied to a rock nd may cause deformination.
  3. 6. boundary- places where plates slide slideways past eachother.
  4. 8. rock- form when hot molten rock crystallizes and solidifies.
  5. 10. zone- zones of fractures between two blocks of rock.
  6. 13. tectonics- plates which move slowley over the underlying mantle.
  7. 17. when tectonic processes put stress on a rock and the rock bends instead of breaking.
  8. 18. the branch of geophysics concerned with the magnetism in rocks that was induced by the earth's magnetic field
  9. 20. cycle- how each of the three major rock types form and break down
  10. 21. behaves as if it constits of bloocka floating on the underlying mantel.
  11. 23. floor spreadig- occurs at divergent plate boundaries, as tectonic plates slowly move away.
  12. 24. a solid substance with a fairly well defined chemical composition
Down
  1. 1. rigid outer part of the earth, consisting of the crust and upper mantel.
  2. 2. boundary-when two plates come together
  3. 5. rock- form around once living oganisms.
  4. 7. upper layer of the earth's mantle
  5. 9. changing in shape or distorting
  6. 11. boundary- occurs when two tectonic plates move away from eachother
  7. 12. rock- formed in high heat, high pressure
  8. 14. drift- continents move over time
  9. 15. fractures between two blocks of rock
  10. 16. a mountain having a crater through which lava has been created
  11. 19. hardness scale- way to identify minderals
  12. 21. arc- a chain of volcanic islands near the ocean
  13. 22. changing in shape/size resauting from applied forces.
