Compression is the areas where the particles are closer together. Rarefaction is the areas where the particles are stretched apart.
Electromagnetism is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields.

sound waves travel as longitudinal waves, that is the movement of the wave is in the direction of travel. sound is made by vibrations, therefore sound waves create areas of stretched apart air (rarefactions) and compressed air (compressions) which are areas of low and high pressure respectively.
Sound waves are LONGITUDINAL. This means the direction of the particles is the same as the direction of the wave. Sound waves are a series of compressions (areas of high density) and rarefactions (areas of low pressure). All sound waves are caused by vibrations. They only travel if there is a medium for them to travel along, therefore there is no sound in space, or in a vacuum as it cannot travel.
Compression is the areas where the particles are closer together. Rarefaction is the areas where the particles are stretched apart.
Diffusion is the form of passive transport that moves particles away from areas with more particles into areas with fewer particles.
they are called moving particles.
The random movement of particles which happens all the time ensures that they move into any space between other particles. This is called diffusion.
rarefaction
Active transport usually involves the movement of particles from high to low concentration.
Diffusion
Van Allen Radiation Belt
Diffusion is the form of passive transport that moves particles away from areas with more particles into areas with fewer particles.
Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air donot vibrate in a transverse manner.Soundis produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.
You are describing the process of diffusion.
Such areas are called Van Allen belts.
