Q.5. Give geographical reasons. 1) Primary or 'p' waves are also called forward-backwards waves.2 ) Secondary waves are more destructive than primary waves​

Answer»

S waves are called secondary waves because they always ARRIVE after P waves at SEISMIC recording stations. Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of EARTH, they are followed by surface waves, which travel along Earth's surface.Explanation:PLEASE mark as brilliant
