Rarefaction
When one part of a vibration causes air particles to spread out, they form ararefaction
Compression
Sound is a form of vibration.
Sound is considered to be a type of kinetic energy because it is a form of energy that is produced by the movement of objects or particles. Kinetic energy is any energy that is in motion and sound is produced by the vibrational motion of particles. The energy of sound is created by the movement of air particles which are set in motion by a vibrating object. This vibration produces sound waves which travel through the air until they reach our ears. Sound is an example of kinetic energy because it requires motion to be produced. This motion is created by the vibration of an object which causes molecules in the air to vibrate or oscillate. This vibration is then picked up by our ears and interpreted as sound. The energy of the sound is a result of this vibration and is therefore considered a form of kinetic energy. Sound is also considered a type of kinetic energy because it carries energy with it as it moves through space. This energy is in the form of sound waves which are created by the vibration of objects and particles. As the sound waves move they carry energy with them which can be converted into other forms of energy. This is why sound is considered to be a form of kinetic energy.
In case of movement Kinetic energy and in case of vibration both Potential and Kinetic energy. While vibrating, in the extreme position, only PE and while crossing mean position only KE. At other positions both KE and PE.

Compression
Sound is, in its most basic form, a vibration of particles. Sound energy, then, is carried from one place to another by the transmission of vibrations from particles to surrounding particles.
Particles that have been coagulated and been brought together to form a larger agglomeration.

agglutination =D
When a comet nears the sun, and begins to out-gas, solar wind pushes the particles away. as the comet nears the sun, more & more particles are emitted, and the tail grows.
