Which of the following statements describe s-waves? select the two correct answers a. they can only travel through the solid rock inside earth. b. they are the most destructive earthquake waves. c. they are the second type of waves detected after an earthquake. d. they alternately compress and pull apart the particles in matter.

The statements that are true for S-waves are:

A.They can only travel through the solid rock inside Earth.

C.They are the second type of waves detected after an earthquake.

The S-wave is the second wave that gets detected by the seismograph. These waves do not travel through the liquid medium. They are also slower than the initially detected P-waves. S-wave also are more destructive than the P-waves but are relatively less destructive than the L-waves and the Rayleigh waves.

A and C would be your answers for this
