Which statement correctly describes how a sound travels through air?

• The wave moves through the air and gains energy from the moving molecules that it touches.

• the wave carries a molecule in one direction until it collides with another molecule

• the wave carries energy that causes molecules to move back and forth

• the wave carries molecules of air away from the source of the sound
