WebS waves are a type of shear wave that can only travel through solids, not liquids. Therefore, the absence of S waves in certain areas suggests that the seismic waves are being blocked by a liquid layer within the Earth's interior. This led geologists to develop a model of the Earth's interior with a solid mantle and a liquid core.
