Across
  1. 1. Crust Thin, dense crust (mostly basalt).
  2. 4. Core Solid sphere of iron and nickel.
  3. 7. The thick, hot, solid/plastic layer between crust and core.
  4. 9. The plastic, flowing layer of the upper mantle below the lithosphere.
  5. 10. The lower, more rigid part of the mantle.
  6. 13. The ability of solid rock to flow slowly.
  7. 14. Energy Heat from within the Earth.
  8. 15. Crust: Thick, less dense crust (mostly granite).
  9. 16. Mass per unit volume, which dictates layer separation.
  10. 18. The outermost, solid layer.
Down
  1. 2. Heat transfer in the mantle (rising hot material, sinking cool).
  2. 3. The rigid outer layer, including the crust and upper mantle.
  3. 5. Process where one plate dives beneath another.
  4. 6. Current The circular motion caused by convection.
  5. 7. Molten rock beneath Earth's surface.
  6. 8. The innermost, dense, metallic center (iron/nickel).
  7. 11. Force exerted on a layer, increasing with depth.
  8. 12. Core Liquid layer of iron and nickel.
  9. 13. Tectonics The theory of moving lithospheric plates.
  10. 17. Waves Vibrations that travel through the interior.
