The wave carries energy that causes molecules to move back and forth.

Explanation: Sound is a mechanical (longitudinal) wave that transmits energy through the air by causing local oscillations of air molecules parallel to the direction of propagation. The molecules mostly oscillate about their equilibrium positions — there is no net transport of air away from the source.
