  4. 9. second seismic wave to arrive, can only travel through solids
  5. 10. a fracture or series of fractures between two blocks of rock
  6. 12. first seismic wave to arrive, can travel through solids, liquids and gases
  7. 13. a force that pushes on or squeezes a material
  8. 15. force directed parallel to a surface
  9. 16. usually made of wood or metal placed diagonally in an x shape to resist sideways motion
Down
  1. 1. stress due to twisting forces exerted on a body
  2. 2. a wave of energy that travels through the Earth
  3. 4. giant waves caused by earthquakes or volcanic eruptions
  4. 6. type of plate boundary where two plates slide past one another and can result in earthquakes
  5. 8. stress that occurs when forces act to stretch an object
  6. 11. an assembly of structural members joined to form a rigid frame work, usually connected to form triangles
  7. 14. a stiff wall that imparts lateral force resistance on a building frame
