Across
  1. 2. caused when materials are compressed, bent, or stretched and return to original shape
  2. 4. erupted materials
  3. 5. lava reaches the surface by traveling through this tube-like structure
  4. 6. the point of failure where waves originate
  5. 10. a fracture or system of fractures along which Earth moves
  6. 11. total force acting on crustal rocks per unit of area
  7. 12. composed of layers of lava from non-explosive eruptions and materials that pile around the vent after an eruption
  8. 13. small volcanoes with steep slopes; composed of materials of materials that pile around vent after an eruption
  9. 14. smallest pieces of erupted materials
  10. 15. along this type of boundary rock is squeezed causing reverse faults to form; earthquakes can be very strong and deep
Down
  1. 1. resistance to flow
  2. 2. the point on the earth's surface directly above a focus
  3. 3. along this type of boundary a normal fault will form; earthquakes tend to be shallow because crust is thin
  4. 4. along this type of boundary shear stress pushes plates in opposite directions; earthquakes are relatively shallow
  5. 7. large volcanoes with gentle slopes; composed of layers of lava from non-explosive eruptions
  6. 8. large depressions that form after the magma chamber empties
  7. 9. lava emerges through this opening
  8. 12. bowl-shaped depression around the vent of a volcano
