For each statement below, write true or false. 5. Seismic waves change speed and direction when they encounter different materials. 6. P-waves travel through Earth's mantle. 7. S-waves do not travel through Earth's mantle. 8. Surface waves are the first to arrive at a seismic station. 9. P-waves are bent when they strike the core. 10. On seismograms, seismic waves recorded from more distant facilities are closer together than those recorded from facilities close to the epicenter. 11. S-waves do not enter the core because they cannot travel through solids. 12. Seismologists have reasoned that Earth's outer core must be liquid based on the disappearance of S-waves. 13. Studies of how waves reflect deep inside Earth show that Earth's inner core is solid. 14. The P-wave shadow zone does not receive direct P-waves.
