Shear waves do not pass through a solid-liquid boundary between Earth's layers. Compressional waves can pass this type of boundary.

Question

Quizplus · Accepted Answer

This statement is true. Shear waves are transverse waves that propagate only through solid materials, while compressional waves are longitudinal waves that can pass through both solid and liquid materials. Therefore, only compressional waves can travel through a solid-liquid boundary between Earth's layers.
