Across
  1. 5. Earth's layers that are divided by their chemical composition or mixture
  2. 7. only liquid layer of the Earth; lies beneath the mesosphere
  3. 10. completely solid layer and has the most density; extends from the outer core to the center of the Earth
  4. 11. these are currents that cause the movement of the lithosphere; can be found in the asthenosphere
  5. 12. the lower portion of the mantle
  6. 13. layer of the Earth found between the crust and the core
Down
  1. 1. layers of the Earth that are divided based on the states of matter found in each layer
  2. 2. the thin, outermost layer of the Earth
  3. 3. one category of the Earth's crust that is thicker, but has less density
  4. 4. one category of the Earth's crust that is thinner, but has more density
  5. 6. layer of the Earth located below the lithosphere; able to flow like putty or plastic; convection currents are found here
  6. 8. layer of the Earth composed of the crust and the upper part of the mantle
  7. 9. the layer of Earth that is below the mantle and extends to the center of Earth
