Across
  1. 7. the transfer of heat by circular currents in a fluid; in earth science, the process in the mantle that moves the continental plates above
  2. 9. a type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions
  3. 12. physical layer in which convection occurs
  4. 15. a scale ranking ten minerals from softest to hardest; used in testing the hardness of minerals
  5. 17. a substance that cannot be broken down into simpler substances; made of only one kind of atom
  6. 19. not formed from living cells or from the remains of living things
  7. 20. a type of rock that forms from the cooling of molten rock at or below the surface
  8. 21. process in which sediment is laid down in new locations
  9. 22. the tendency of a mineral to break unevenly or irregularly, with no flat surfaces
  10. 24. a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
  11. 25. the chemical and physical processes that break down rock at Earth's surface
  12. 27. processes by which particles of rock, sand, and soil are carried away by wind or flowing water
  13. 28. physical layer consisting of the strong, lower part of the mantle between the asthenosphere and the outer core
  14. 29. layers in which similar physical processes occur (lithosphere, asthenosphere, mesosphere, outer core, inner core)
Down
  1. 1. compositional layer of hot, solid material between Earth's crust and core
  2. 2. a mineral's ability to split easily along flat surfaces
  3. 3. rigid physical layer composed of the crust and upper mantle
  4. 4. smallest particle of an element
  5. 5. a measure of how easily a mineral can be scratched
  6. 6. the series of processes that change one type of rock into another type of rock
  7. 8. layers made of the same things (crust, mantle, core)
  8. 10. the color of a mineral in powdered form as left on a ceramic plate
  9. 11. a type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together
  10. 13. liquid physical layer that lies beneath the mesosphere and surrounds the inner core
  11. 14. a solid, inorganic structure arranged in a repeating three-dimensional pattern
  12. 16. small, solid pieces of material that come from rocks or living things
  13. 18. the layer of rock that forms Earth's outer surface (compositional layer)
  14. 23. the degree to which a rock or mineral interacts with and reflects light
  15. 26. a physical layer consisting of a dense sphere of solid iron and nickel at the center of Earth
