GEOLOGY

Detailed explanation-1: -Surface waves (yellow concentric lines) travel slower than body waves and along the surface of the Earth generating two types of waves: Love waves and Rayleigh waves. Love waves move side-to-side at right angles to the propagation direction.

Detailed explanation-2: -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-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 are slower than P-waves. They are transverse waves, which means that the particle motion is at right angles to the direction of travel.

Detailed explanation-5: -S waves are transverse waves, meaning that the direction of particle motion of a S wave is perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress.
