"Sound waves and some earthquake waves have compressions and rarefactions."

Reason: sound waves are longitudinal (compressions and rarefactions). Among seismic waves, P (primary) waves are also longitudinal (compressions/rarefactions), but S (secondary) waves and many surface waves are transverse or complex, so not all earthquake waves have compressions and rarefactions.
