Across
  1. 4. an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide
  2. 6. a long high sea wave caused by an earthquake, submarine landslide, or other disturbance
  3. 7. states that parts of the Earth's crust slowly drift atop a liquid core
  4. 11. a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge
Down
  1. 1. plates are coming apart
  2. 2. divergent, convergent, and transform
  3. 3. a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere
  4. 5. a long, narrow ditch
  5. 7. the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other
  6. 8. the concerted, collective movement of groups
  7. 9. plates slide past each other
  8. 10. the result of a sudden release of energy in the Earth's crust
  9. 11. the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge
  10. 12. running along the Mid Atlantic Ridge
