Across
  1. 3. soft, weak/high plasticity; upper mantle only
  2. 5. transverse waves are slower and can only travel through solid portions of Earth's interior.
  3. 7. plates move away from each other, forming oceanic ridges, rift zones/valleys, volcanoes, and/or earthquakes
  4. 8. continental when 2 continental plates collide, the lithosphere buckles and pushed upward, forming mountain ranges
  5. 9. push occurs when a newly-formed lithosphere next to a ridge slides down away from the ridge.
Down
  1. 1. when a continental plate and oceanic plate collide, the oceanic plate subduct because its more dense, forming trenches and volcanic arcs.
  2. 2. cool, and rigid; includes the crust and upper mantle
  3. 4. Pull occurs when the sinking of a subducting plate pulls the rest of the plate across the asthenosphere
  4. 5. Waves. travel along earths surface and cause the most damage at the surface.
  5. 6. plates move towards each other, forming ocean trenches (at subduction zones), mountains volcanoes, and/or earthquakes
