GEOLOGY

Detailed explanation-1: -P waves are the fastest seismic waves and can move through solid, liquid, or gas.

Detailed explanation-2: -P waves can move through solid rock and fluids, like water or the liquid layers of the Earth. It squishes and stretches the rock it moves through just like sound waves compress and expand the air as they move through it.

Detailed explanation-3: -Table 1 Properties of P-waves and S-waves P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km.

Detailed explanation-4: -P waves are compressional. They vibrate parallel to the direction the wave is moving.

Detailed explanation-5: -P waves expand and contract rock particles These waves travel in all directions away from the focus of an earthquake. P waves are energy waves that cause rock particles inside the earth to expand and contract like the slinky in the picture as they move through the body of the Earth.
