Detailed explanation-1: -P waves travel through solid and liquid, but S waves do not travel through liquid.
Detailed explanation-2: -P waves are able to travel through both solid rock (such as granite) and liquid material (such as volcanic magma or water), while S waves are only able to travel through solid rock.
Detailed explanation-3: -P-waves travel through liquids and gases as well as through solids. Although liquids and gases have zero rigidity, they have compressibility, which enables them to transmit P-waves. Sound waves are P-waves moving through the air.
Detailed explanation-4: -Secondary waves (also called shear waves, or S waves) are another type of body wave. They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves.
