Which statement correctly describes how a sound wave travels through air?

The wave moves the molecules of air away from the source of the sound.

The wave transfers energy that causes the air molecules to vibrate back and forth.

The wave moves an air molecule in one direction until it collides with another molecule.

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