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