Across
  1. 1. the thin and solid outermost layer of the ear above mantle.
  2. 4. the series of processes in which a rock forms changes from one type to another is destroyed and forms again by geologic processes.
  3. 6. the process of returning land to the original condition after mining it completed.
  4. 8. the process by which wind water ice or gravity transports soil and sediment from one location to another.
  5. 9. the body of molten rock that feeds a volcano.
  6. 13. the soft layer of the mantle on which the tectonic plates move.
  7. 14. a substance that can not be separated or broken down into simpler substances by chemical means.
  8. 18. the solid outer layer of the earth consist of the crust and rigid upper of the mantle.
  9. 19. an opening at the surface of the earth through which volcanic material passes.
  10. 21. the color of the powder of a mineral.
  11. 23. a naturally occurring solid mixture of one or more minerals or organic matter.
  12. 25. the manner in which a mineral breaks along either curved or irregular surface.
  13. 28. a large semicircular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink.
  14. 29. a naturally formed inorganic solid that has a definite crystalline structure.
  15. 31. a wide flat land form that results from repeated nonexplosive eruptions of lava that spreads over a large area.
  16. 32. a substance made up of atoms of two or more different elements joined by chemical bonds.
  17. 33. an area of deep cracks that form between two tectonic plates that are pulling away from each other.
  18. 34. a volcanic active area of earths surface far from a tectonic plate boundary.
Down
  1. 2. a mineral that contains a combination of silicon oxygen and one or more metals.
  2. 3. a vent or fissure in the earths surface through which magma and gases are expelled.
  3. 5. the ratio of the mass of substance to the volume to the substance.
  4. 7. the strong lower part of the mantle between the asthenosphere and the outer core.
  5. 10. the splitting of a mineral along smooth flat surfaces.
  6. 11. the central part of the earth below the mantle.
  7. 12. the quality of a rock that is based on the sizes shapes and position of the rocks grain.
  8. 15. a mineral that does not contain compound of silicon oxygen.
  9. 16. the way in which a mineral reflects light.
  10. 17. the process in which material is laid down.
  11. 20. a solid whose atoms ions or molecules are arranged in a definite pattern.
  12. 22. a natural material to be mined profitably.
  13. 24. the layer of rock between the earths crust and core.
  14. 26. a funnel shaped pit near the top of the central vent of a volcano.
  15. 27. a block of lithosphere the consist of the crust and the rigid outermost part of the mantle.
  16. 30. a measure of the ability of mineral to resist scratching.
