Properties of Compressional or P waves. The first kind of body wave is the P wave. This is the fastest kind of seismic wave their name derives for the fact that P is an abbreviation for primary, first wave to arrive. The P wave generally travel at speeds between 1 and 14 km/sec. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
Sound travels fastest in solids because the constituent particles (atoms/molecues/ions) are most closely/tightly packed. Sound is a longitudinal wave, which means that sound waves travel through the vibrations of individual particles of matter (compressions and rarefactions) which are along the direction on propogation. Only the disturbance is transmitted forward, without requiring the particles to actually move themselves.
