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: -Answer and Explanation: Only the P waves can reach the Earth’s inner core. P waves and S waves are both body waves, or seismic waves that can propagate through the Earth’s interior.

Detailed explanation-3: -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.

Detailed explanation-4: -P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid, or gas.

Detailed explanation-5: -P-waves are the first waves to arrive on a complete record of ground shaking because they travel the fastest (their name derives from this fact-P is an abbreviation for primary, first wave to arrive). They typically travel at speeds between  1 and  14 km/sec.
