  1. 2. Flows like asphalt under heavy weight
  2. 4. Mostly solid rock that floats on top of the asthenosphere.

  4. 7. The outer most layer of the earth, also the most thin.
  5. 8. Made of solid Nickel and Iron. Has a very high temperature and pressure. About 800 miles thick.
  6. 10. The crust plus the upper mantle.
Down
  1. 1. When these move they give the crust a "free ride"
  2. 3. Liquid Nickel and Iron. About 1400 miles thick.
  3. 6. Reason the continental plates move.
  4. 9. Extremely hot part of the mantle that exists as both solid and liquid.
