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