Question

Earthquakes produce p waves, which are longitudinal waves that travel underground. how do these waves move through the soil and rock?

Answer 1

As a series of compressions and rarefactions... hope it helps :)

Answer 2

The wave moves with compression and rarefaction alternately.

Step-by-step explanation:

p waves are longitudinal waves and we know that longitudinal waves have vibrations parallel to its direction of motion. In one region where the particles comes closer is known as compression and region where the particles move farther from each other, is known as rarefaction. p waves travel through soil and rock as sequence of rarefaction and compression alternately.
