Detailed explanation-1: -Seismic surface waves travel along the Earth’s surface. They can be classified as a form of mechanical surface waves. They are called surface waves, as they diminish as they get farther from the surface. They travel more slowly than seismic body waves (P and S).
Detailed explanation-2: -Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water.
Detailed explanation-3: -Answer and Explanation: The only statement that is true is that the p-waves or primary waves travel faster, and thus arrive sooner than do the s-waves or secondary waves which is choice B.
Detailed explanation-4: -Therefore, seismic waves can be described as waves of energy that are generated from a sudden breaking of rocks within Earth.
Detailed explanation-5: -There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.
