Why is a large S-wave shadow zone formed?

Answer and explanation

Correct answer: Because S-waves cannot pass through the liquid outer core

S-waves, or secondary seismic waves, are shear waves and require a solid medium to travel. Earth’s liquid outer core does not transmit them, creating a broad region on the far side of Earth where they are not directly detected. This shadow zone is important evidence that the outer core is liquid.
