Across
  1. 3. formed within Earth’s crust when magma cools and hardens
  2. 4. cycle process by which rocks continually change from one rock type to another
  3. 7. consists of inner and outer layers (~15% of Earth)
  4. 8. through a geological process
  5. 10. largest layer (~84%) of Earth
  6. 11. hard, rigid outermost layer of Earth (the outer “skin”)
  7. 12. forms as magma or lava cools and solidifies
  8. 15. any solid mass of mineral or mineral-like matter that occurs naturally as part of
  9. 16. formed when sediment goes through compaction and cementation
  10. 17. small pieces of rock or living things, formed through the processes of
  11. 18. the breaking down of rocks
  12. 19. thinner crust, more dense crust (mostly basalt)
  13. 21. solid iron or nickel layer, moon sized
Down
  1. 1. thicker crust, less dense crust (mostly granite)
  2. 2. hard,rigid layer (bottom of crust PLUS top of mantle=plates)
  3. 5. only true liquid layer
  4. 6. and erosion
  5. 8. the removal of the material
  6. 9. field created by rotation of inner and outer cores
  7. 13. formed on Earth’s surface when lava cools and hardens
  8. 14. formed when a parent rock is put under extreme pressure or heat
  9. 20. heat driven cycles that occur in the mantle caused by differences in
