WebThe density of the mantle also increases at greater depth, which has the effect of reducing the speed of seismic waves, but the increase in rigidity is much greater than the increase in density, so S-waves speed up as they get deeper in the mantle, in spite of the increased density. Surface Waves bowen island places to stayWebThe movement of the particles is now on a perpendicular axis to the actual movement of the waves. And so that's what an S-wave is. And they move a little bit slower than the P … gujarati textbook solutions class 8WebSeismic waves travel faster in denser rocks; temperature tends to lower the speed of seismic waves; and pressure tends to increases the speed.
