  1. 2. small, steep-sided volcanoes that erupt gas-rich, basaltic lavas
  2. 3. waves that cause particles in the ground to move in a push-pull motion similar to a coiled spring
  3. 4. the vibrations in the ground that result from movement along breaks in Earth’s lithosphere
  4. 6. Scientists that study earthquakes
  5. 7. graphical illustration of seismic waves
  6. 8. volcanoes that are not associated with plate boundaries
  7. 11. common along divergent plate boundaries and oceanic hotspots. Shield volcanoes are large with gentle slopes of basaltic lavas
  8. 14. - a liquid’s resistance to flow
  9. 15. a break in Earth’s lithosphere where one block of rock moves toward, away from, or past another
  10. 16. waves that cause particles in the ground to move up and down in a rolling motion
  11. 17. molten rock below Earth’s surface
Down
  1. 1. the location on Earth’s surface directly above the earthquake’s focus
  2. 2. large, steep-sided volcanoes that result from explosive eruptions of andesitic and rhyolitic lava and ash along convergent plate boundaries
  3. 5. measures and records ground motion and can be used to determine the distance seismic waves travel
  4. 6. energy that travels as vibrations on and in Earth
  5. 9. waves that are slower than primary waves and cause particles to move up and down at right angles relative to the direction the wave travels
  6. 10. molten rock that erupts onto Earth’s surface
  7. 12. tiny particles of pulverized volcanic rock and glass
  8. 13. a location inside Earth where rocks first move along the fault, creating seismic waves
  9. 14. a vent in Earth’s crust through which melted- or molten -rock flows
