Why do series of compressions and rarefactions take place?

have you seen spring/slinky?
notice it . produce jerk at one end..then things will be clear.
this is property of any elastic medium.....if we disturb it at one place it will always try to regain its original shape and size...so in doing so a successive compression and ratrefaction is already produced.
