Surface waves travel normally on the layer of the earth whereas body wave’s movement is in the interior of the earth. The facts on which body waves are divided is their mode of transmission and propagation .P waves normally push and pull the rock in the direction of wave motion , whereas S waves shake the ground in the direction of right angle .P waves can pas through soil, liquid and gases whereas S waves cannot pass through liquids and gases . Travel time for P waves is mush greater then the S waves. P waves travel with the speed of 6 kilometer /sec whereas S waves travel with the speed of 3 kilometer /sec. It is a fact that as surface waves is generated on the surface
