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