Let us now check the veracity of each of the given statements.Ī. All these different types of waves have their own unique features. The body waves are divided into P-waves (primary waves) and S-waves (secondary waves). The body waves travel through the different layers of the Earth and the surface waves travel at the Earth's surface. Seismic waves are broadly classified into two types- the surface waves and the body waves. Seismic waves are waves of energy which move through the layers of the Earth's interior and the surface. It always takes the path where there is least resistance. The path which the waves follow depends on the surroundings. So not every kind of wave will reach the surface. Not all kinds of seismic waves can travel through all the layers of the Earth. Earthquake damage also results from Rayleigh waves, surface waves which deform materials vertically.Hint: P-waves and S-waves have different properties and therefore travel differently. #SEISMAC WAVE SHADOW ZONE CRACKED#This cracked pavement and these twisted railroad tracks clearly demonstrate their destructive power. One type of surface wave, the Love wave, travels in a circular motion and causes damage by displacing materials horizontally. The slower seismic surface waves do not penetrate the earth's interior, but follow the surface. For this reason, there is also an S wave shadow-zone. Because secondary waves travel only through solids, they do not penetrate the earth's outer molten core. S waves are elastic shear waves that move material sideways, at right angles to their direction of travel. The slowest body waves are secondary, or "S" waves. Because they are deflected by the earth's core, P waves are not seen in the so-called shadow-zone. These compressional waves move faster in dense rock and slower in fluids. The fastest of these are primary, or "P," waves. Body waves travel through the interior of the earth. NARRATOR: Earthquakes generate two main types of seismic, or shock, waves: body waves and surface waves.
