This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
the answer is A
A. P waves is a earthquake wave type that can travel through both solids and liquids.
P waves are seismic wave in seismology that is characterized by arriving the seismic station at fastest time. It stands for pressure waves which are composed of rarefactions and consecutive compressions.
The Pressure wave can travel across solid rock and fluids. For example, it can travel through water or the liquid layers of the earth. This is the first arriving signal for the earthquake in the seismograph. Hence, advance warning may be detected by the seismic waves generated from the earth's crust.
