Explanation: 

Detailed explanation-1: -Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

Detailed explanation-2: -P-wave and S-wave paths through the earth. Scientists discovered that Earth’s outer core is liquid by observing seismic waves. P waves travel through solid and liquid, but S waves do not travel through liquid.

Detailed explanation-3: -Not all kinds of seismic waves can travel through all the layers of the Earth. So not every kind of wave will reach the surface. The path which the waves follow depends on the surroundings.
