Across
  1. 3. The recorded output of a seismograph.
  2. 4. Solid, dense center of Earth.
  3. 10. Increase in temperature as depth increases.
  4. 12. Thin, outer layer of Earth where we live.
  5. 13. Area where certain seismic waves are not detected.
  6. 14. Point underground where the earthquake begins.
  7. 16. Smaller quake before the main earthquake.
  8. 18. Thick layer of hot, solid rock beneath the crust that flows slowly.
  9. 19. Soft, plastic-like layer beneath the lithosphere that can flow.
  10. 20. Study of earthquakes and seismic waves.
  11. 22. Sudden shaking caused by energy release in Earth’s crust.
  12. 23. Slower waves; travel only through solids.
  13. 24. Fastest waves; travel through solids, liquids, and gases.
Down
  1. 1. Rigid outer layer made of the crust and upper mantle.
  2. 2. Stress builds up and is released suddenly, causing earthquakes.
  3. 5. Center of Earth made mostly of iron and nickel.
  4. 6. Force exerted on an area; increases with depth.
  5. 7. Smaller quake after the main earthquake.
  6. 8. Liquid layer that surrounds the inner core.
  7. 9. Break in Earth’s crust where movement occurs.
  8. 11. Point on Earth’s surface directly above the focus.
  9. 13. Tool used to detect and record seismic waves.
  10. 15. Travel along Earth’s surface; cause the most damage.
  11. 17. Mass per unit volume.
  12. 18. Lower mantle; more rigid due to pressure.
  13. 21. Energy waves released by earthquakes.
