GEOLOGY

Detailed explanation-1: -Unlike P-waves, S-waves can only travel through solids.

Detailed explanation-2: -S waves can only travel through solids, and scientists have successfully mapped the earth’s interior by studying the routes of these waves. P waves or Primary waves are the first waves to hit the seismographs when an earthquake strikes.

Detailed explanation-3: -S-waves are shear waves, which move particles perpendicular to their direction of propagation. They can propagate through solid rocks because these rocks have enough shear strength.

Detailed explanation-4: -S-waves can only move through solids. This is because liquids and gases don’t resist changing shape. P-waves and S-waves are the two types of body waves.

Detailed explanation-5: -S-waves cannot travel through liquids. When they reach the surface they cause horizontal shaking. Liquids don’t have any shear strength and so a shear wave cannot propagate through a liquid. Think of a solid material, like a rock.
