==Key Stage 4==
===Meaning===
'''P-waves''' are [[longitudinal]] [[Seismic Wave|seismic waves]] that travel through the [[Earth]] during an [[earthquake]].
===About P-waves===
: '''P-waves''' are known as '''primary waves''' because they travel faster than [[S-wave]]s so they arrive at detectors first.
: '''P-waves''' are [[longitudinal]] because they are [[wave]]s of [[compression]] moving through the [[Earth]].
: '''P-waves''' can travel through both [[solid]]s and [[liquid]]s.
: '''P-waves''' are [[refract]]ed as they move through the [[Earth]] because different layers of the [[Earth]] have different [[density]].
: [[Seismic Wave|Seismic]] detectors can be used to observe [[P-wave]]s at different locations on [[Earth]] during an [[earthquake]] and this information can be used to determine the structure of the [[Earth]].
