Best Answer: A P-Wave (Primary Wave) is a seismic wave or compression wave that travels through gases, elastic solids (like clay) and liquid (like water).It moves by vibrating the molecules next to it and continuing that vibration along down the line until it is dampened out.est Answer: A P-Wave (Primary Wave) is a seismic wave or compression wave that travels through gases, elastic solids (like clay) and liquid (like water).
