describe the wave motion and mechanical wave movement of a seismic p wave.

P waves are a type of seismic wave that is characterized by being a longitudinal mechanical wave, which means that the medium through which they travel is alternately compressed and dilated in the same direction of propagation. This means they propagate in a similar way to the sound.

These waves are faster than the S waves, so when an earthquake occurs these waves are the first to be recorded by the seismograph. They can also travel through any type of material (solid, liquid or gaseous), this means they are able to travel through solid rocks as well as in oceans or volcanic magma and are even able to be transmitted through the atmosphere, that is why they are sometimes perceived by people and animals as a deep sound.
