Earth Science Name_____________________________ Chapter 6 Period_____________________________ Worksheet Date______________________________ __________________________________________________________________________________ Earthquake Characteristics Earthquake Diagrams (0.25 points each) Fill in the blanks associated with each diagram by choosing the correct word or words from the list below. L-Wave Focus Seismic waves Fault Fault P-Wave _______________ 9. Which earthquake waves do the most damage? _______________ 10. Which earthquake waves cannot travel through liquid? S-Wave Epicenter Seismic Waves (0.25 points each) The figure (Figure 15.1) below illustrates the paths through the Earth taken by seismic waves set in motion by an earthquake. The locations of five seismograph stations are indicated by the letters A, B, C, D, and E. In the space next to each seismogram below, write the letter of the station that would record that pattern of seismic waves. _____ 11. _____ 12. _____ 13. _____ 14. _____ 15. Seismic Waves Matching (0.25 points each) Column A below lists descriptions of certain effects. The items in Column B are causes. In the space provided beside each effect, write the letter of the cause that brought about that effect. A _____ 16. S-Waves stop moving when they reach the boundary between the mantle and the core. _____ 17. Although an earthquake occurs, a seismograph station receives no seismic waves. _____ 18. As they travel through Earth’s interior, seismic waves do not follow straight paths. _____ 19. P-Waves and S-Waves arrive almost simultaneously at a seismograph station. _____ 20. The velocity of seismic waves increases as the waves cross the Moho. B A. The station is located at or near the epicenter of the earthquake. B. Earth’s outer core is liquid. C. The nature and density of the materials that make up Earth’s interior vary considerably with depth. D. The station is in the shadow zone. E. The materials that make up the mantle are denser than those that make up the crust.
