Detailed explanation-1: -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-2: -Which statement describes P waves? They start as surface waves.
Detailed explanation-3: -P waves travel through solid and liquid, but S waves do not travel through liquid.
Detailed explanation-4: -A P wave is a sound wave traveling through rock. In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases.
