Across
  1. 3. a type of seismic wave that causes particles in the ground to move up and down in a rolling motion
  2. 5. the dense, metallic center of Earth
  3. 8. a graphical illustration of seismic waves
  4. 10. the mass per unit of volume of a substance
  5. 11. the change in direction of a wave away from a boundary the wave encounters
  6. 12. a ball shape with all points on the surface at an equal distance from the center
  7. 13. molten rock stored beneath Earth's surface
  8. 14. a location inside Earth where rocks first move along a fault and from which seismic waves originate
  9. 15. the outer part of Earth's magnetic field that interacts with charged particles
  10. 17. the transfer of heat by the mass movement of heated particles into an area of cooler fluid
  11. 18. scientist that studies earthquakes
  12. 22. a type of seismic wave that causes particles to move at right angles relative to the direction the wave travels
  13. 24. the rigid, outermost layer of Earth that includes the uppermost mantle and crust
  14. 26. a type of seismic wave which causes particles in the ground to move in a push-pull motion similar to a coiled spring
  15. 27. the thick middle layer in the solid part of Earth
Down
  1. 1. an unusually large sea wave produced by a seaquake or undersea volcanic eruption
  2. 2. energy that travels as vibrations on and in Earth
  3. 4. The bending of a wave as it passes from one medium to another medium of different density
  4. 6. vibrations caused by the rupture and sudden movement of rocks along a break or a crack in Earth's crust
  5. 7. an attractive force that exists between all objects that have mass
  6. 9. the locations on Earth's surface directly above an earthquake's focus
  7. 16. the partially melted portion of the mantle below the lithosphere
  8. 19. an instrument that measures and records ground motion and can be used to determine the distance seismic waves travel
  9. 20. a crack or a fracture in Earth's lithosphere along which movement occurs
  10. 21. the solid part of Earth
  11. 23. a liquid layer about 2,266 km (1,408 mi) composed of iron and nickel which lies above the Earth's solid inner core and below its mantle
  12. 25. the brittle, rocky outer layer of Earth
