GEOLOGY

Detailed explanation-1: -In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation.

Detailed explanation-2: -P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave is moves in; it is the direction that the energy is traveling in, sometimes called the “direction of wave propagation.”

Detailed explanation-3: -type of seismic wave P waves are compressional waves and travel at the highest velocity; hence, they arrive first. S waves are shear waves that travel at a slower rate and are not able to pass through liquids that do not possess…

Detailed explanation-4: -A P wave is a sound wave traveling through rock. In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases.

Detailed explanation-5: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
