SOLAR SYSTEM

Detailed explanation-1: -Detailed Description. 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-2: -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. This causes the waves to travel in curved paths.

Detailed explanation-3: -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.

Detailed explanation-4: -Although S-waves are slower than P-waves, they still travel fast, over half the speed of P-waves, moving at thousands of kilometers per hour through the earth’s crust and mantle.

Detailed explanation-5: -P waves are compressional waves that do not produce much damage. They can move through any type of material and travel at almost twice the speed of S waves.
