Across
  1. 1. The thin, outermost layer of the Earth, or the uppermost part of the lithosphere.
  2. 5. The central, spherical part of the Earth below the mantle.
  3. 7. The boundary between two tectonic plates that are moving away from each other.
  4. 8. The layer between the crust and the core.
  5. 11. The transfer of thermal energy by the circulation or movement of a liquid or a gas.
  6. 12. The boundary between two tectonic plates that are sliding past each other horizontally.
  7. 14. Magma that flows onto the Earth's surface.
  8. 15. An act, process or result of lifting up a part of the Earth's surface.
  9. 16. The theory that the lithosphere is divided into tectonic plates that move around on top of the asthenosphere and mantle.
  10. 17. A shaking or trembling of a portion of the Earth
  11. 18. A mountain that forms when molten rock , called magma, is forced to the Earth's surface.
Down
  1. 2. The region where an oceanic plat sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates.
  2. 3. The boundary between two colliding tectonic plates.
  3. 4. The theory that continents can drift apart from one another and have done so in the past.
  4. 5. The make up of a rock; describes either the minerals or the elements presented in it.
  5. 6. The hot liquid that forms when rock partially or completely melts; may include mineral crystals.
  6. 9. The amount of matter in a given space; mass per unit volume.
  7. 10. A breaking in the Earth's curst along which blocks of the crust slide relative to one another due to tectonic forces.
  8. 13. The outermost, rigid layer that consists of the crust and the rigid upper part of the mantle.
