# What can shear waves travel through?

## What can shear waves travel through?

Shear waves cannot travel in liquids or gases — so, for example, S waves don’t travel through the ocean or through the outer core. Surface waves are called surface waves because they are trapped near the Earth’s surface, rather than traveling through the “body” of the earth like P and S waves.

## What type of waves can travel through liquid?

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.

Can shear waves travel through the interior of the Earth?

S-waves (S stands for secondary) are shear earthquake waves that pass through the interior of the Earth. S-waves don’t change the volume of the material through which they propagate, they shear it.

Why do shear waves only pass through solids?

S-waves can travel only through solids, because only solids have rigidity. S-waves cannot travel through liquids or gases. Because the earth’s mantle becomes more rigid as its depth below the asthenosphere increases, S-waves travel faster as they go deeper in the mantle.

### Which earthquake waves Cannot pass through liquids?

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.

### Which waves travel the fastest?

Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

Which earthquake waves Cannot pass through liquid?

Which is faster P or S wave?

P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
