Which type of seismic wave causes particle displacement perpendicular to the direction of wave propagation, and is notably unable to pass through liquid layers?

💡 Solution & Explanation

Secondary waves are transverse seismic waves that cause particle displacement perpendicular to the direction of wave propagation and cannot travel through liquid media because fluids lack shear strength. Primary waves are compressional and can pass through both solids and liquids, while surface waves travel along the Earth's crust. Seismic wave properties are crucial concepts tested in physical geography and geomorphology.
