GEOLOGY

Detailed explanation-1: -S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side. S waves are called secondary waves because they always arrive after P waves at seismic recording stations.

Detailed explanation-2: -Because S waves only move through solids, seismologists were led to conclude that the Earth’s outer core is a liquid. S waves move rock particles up and down, or side-to-side, and are always perpendicular to the direction that the wave is traveling in (the direction of wave propagation).

Detailed explanation-3: -S waves produce vertical and horizontal motion in the ground surface. Particle motion consists of alternating transverse motion. Particle motion is perpendicular to the direction of propagation (transverse).

Detailed explanation-4: -S waves, also known as secondary waves, are shear waves that arrive after P waves and have a side-to-side motion.

Detailed explanation-5: -S waves produce vertical and horizontal motion in the ground surface. Rayleigh Waves-surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction of wave propagation.
