A: Sound travels as a back-and-forth vibration of the particles of its medium. It is a longitudinal mechanical pressure wave that varies greatly in its speed of travel and the distance it remains coherent, dependent upon the medium. Sound in air travels relatively slowly and for a short distance, while sound in a solid, such as the primary waves of an earthquake, travel extremely quickly and to great distances.
