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. WebGeologists estimate the depths of the Earth's interior layers by studying the ocean basins and sea bed. Geologists make use of the same types of evidence to infer the Earth's interior layers. Satellite imagery provides definitive proof of the gathered data regarding the Earth's mantle and core.
