S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids.
This is evidence that the outer core does not behave like a solid substance.
S-waves are not transmitted through the liquid outer core.
Which seismic waves can travel through the Earth’s liquid outer core?
P waves can travel through the liquid outer core. An S wave is a different beast. In an S wave, the rock particles slide past one another, undergoing shear — so an S wave is also called a shear wave.
Do S waves travel through liquid?
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.
At what point do S waves stop traveling through Earth’s interior?
Waves are also refracted at boundaries within Earth, such as at the Moho, at the core-mantle boundary (CMB), and at the outer-core/inner-core boundary. S-waves do not travel through liquids — they are stopped at the CMB — and there is an S-wave shadow on the side of Earth opposite a seismic source.
What wave P or S Cannot go through the core of Earth?
S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium.
