Across
  1. 3. the rigid outermost layer of Earth that includes uppermost mantle and crust.
  2. 4. super continent that broke apart 200 million years ago
  3. 5. the circulation of particles within a material caused by difference in thermal energy and density
  4. 6. the pulling force at a divergent boundary
  5. 8. a change in the shape of rack caused by stress
  6. 10. deep underwater trough created by one plate subducting under another at a convergent boundary
  7. 11. an area of many fractured pieces of crust along a large fault
  8. 15. fault that forms where tectonic plates slide horizontally past each other
Down
  1. 1. parallel forces acting in opposite direction at a transform boundary
  2. 2. the squeezing force at a convergent boundary
  3. 7. the downward vertical motion of Earth's surface
  4. 9. a curved line of volcanoes that forms parallel to a plate boundary
  5. 12. the process that moves large bodies of Earth's materials to higher elevations
  6. 13. the equilibrium between continental crust and the denser mantle below it
  7. 14. the process that occurs when a tectonic plate moves under another
