Down
  1. 1. a tectonic plate which includes most of the continent of Eurasia
  2. 2. plastic layer in the mantle
  3. 4. a major tectonic plate in the eastern and, largely, southern hemispheres.
  4. 5. made of lithosphere and asthenosphere
  5. 7. formed by divergent plate boundaries
  6. 10. an oceanic tectonic plate that lies beneath the Pacific Ocean.
  7. 13. a major tectonic plate which includes the continent of South America
  8. 15. a major tectonic plate straddling the Equator as well as the prime meridian.
  9. 18. As a slab sinks, it pulls on the rest of the plate with a force
