Answer:

Waves are made up of compressions and rarefactions.

Compression simply means that the material in question (for example air) is pressed together and its density increases. .
Rarefaction is just the opposite, it occurs when molecules are given extra space and allowed to expand. Remember that sound is a type of kinetic energy.
