Across
  1. 7. the densest layer of the earth, mostly made of Fe and Ni
  2. 8. hot fluid below the earths crust
  3. 10. a substance naturally formed in earth
  4. 12. located in the upper most mantle, right below the lithosphere
  5. 14. what the earth is made up of
  6. 16. formed when sediments are weathered, deposited, and eroded to form a new rock
  7. 17. when magma or lava crystallizes, it forms this type of rock
Down
  1. 1. the layer made of all liquid, made of Fe and Ni
  2. 2. a mark (usually a line) made from the surface of a rock
  3. 3. it is part of the mantle and the crust, is right on top of the athenosphere
  4. 4. force put onto a rock
  5. 5. when a rock has lots of heat and pressure it forms a new rock
  6. 6. the thickest layer of earth
  7. 9. bringing together particles
  8. 11. igneous rocks formed from magma forced into older rocks in the earth's crust
  9. 13. how light interacts with the surface of a rock or crystal
  10. 15. the movement of a plate in the earths crust into the mantle beneath another
