C. What are two characteristics of S waves? (2 points)​

S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side (perpendicular to the motion of the S waves energy).S waves are transverse waves, meaning that the oscillations of an S wave's particles are perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress.
