Across
  1. 4. how igneous rocks are formed
  2. 8. where two plate meet at faultlines; this is where most earthquakes and volcanoes occur
  3. 9. the color a mineral leaves when you write with it
  4. 12. when hot magma near the core rises and cooler rock near the crust sinks
  5. 15. this is how metamorphic rocks are formed
  6. 17. found in the middle of a divergent boundary; rocks father from the ridge are older
  7. 19. scale on ability to scratch or be scratched from 1 - 10
  8. 20. boundary where plates collide and mountains form
  9. 21. a bad characteristic to identify minerals with because for many minerals it is the same; gold and pyrite
  10. 23. fresh water Alligator fossil found on all continents; evidence of continental drift
  11. 24. Solid Inorganic Naturally Occurring with Chemical Composition and Crystal Shape; they make up rocks
  12. 25. plates move horizontally past each other
Down
  1. 1. when sediments are squeezed and bonded together permanently
  2. 2. theory that Earth was one giant landmass
  3. 3. when plates spread apart under the ocean
  4. 5. how a mineral reflects light
  5. 6. the breaking up and removal of rocks from an area; how sediments are formed
  6. 7. deepest parts of the ocean and are Found at subduction zones of convergent boundaries
  7. 10. the changing of one rock type to another over time
  8. 11. rocks made from melting and cooling of lava or magma
  9. 13. rocks formed when heat and pressure change other rocks; limestone to Marble
  10. 14. plates separate creating mid ocean ridges or rift valleys
  11. 16. rocks made from pieces of other rocks cemented together
  12. 18. made of less dense granite and makes up the continents
  13. 22. makes up ocean floor and is very dense and made of the igneous rock Basalt
