Across
  1. 2. long crack in the surface on the earth, earthquakes usually occur
  2. 3. tectonic plates that lie under surface land masses
  3. 7. sea floor mountain system formed by divergent boundaries
  4. 8. when two plates move away from each other Ex: rift valley, mid ocean ridge
  5. 9. when two tectonic plates move towards each other and collide Ex:uplift, mountains
Down
  1. 1. parallel pattern of rock material found at identical locations across the Mid-Atlantic Ridge
  2. 4. when two plates slide past each other Ex: fault lines
  3. 5. when a denser plate is pushed down and beneath a less dense plate, creates volcanoes
  4. 6. tectonic plates that are at the bottom of the ocean
