P waves are longitudinal mechanical waves which are formed from alternating compressions and rarefactions. In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.The particles do not move with the wave; they simply oscillate back and forth about their individual equilibrium positions. Thus particles in the ground move or vibrate along or parallel to the traveling direction of the P wave when it passes through them..

Rayleigh waves (which are a type of surface wave) produce the largest amplitude and so most severe ground movements during earthquakes.Surface waves produce the most severe ground movements. They produce movements similar to waves in the water, where the water's particles move in a pattern that is almost circular. Surface waves can make the ground roll like ocean waves or shake buildings from side to side. They move more slowly then P waves or S waves.
It need not go up and down. Assuming the wave moves "forward", the individual particles may move up and down, or left and right - or diagonally. In any case, the individual particles move at right angles to the movement of the wave, because that is what "tarnsverse" means.
secondary
particles of matter are packed more loosely in the ground than in the air.
S Waves
waves move through a particle.
False, as P waves move through the ground, they cause it to compress and then expand. P waves are the first to arrive and can damage buildings.
the answer to this question is transverse wave
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
sound waves move along with the particles of matter through which it passes

The particles of the wave (for compressive waves). Or for transverse waves, yet the particles move parallel to the wave too.
S waves cause rocks particles to move from side to side. The rock particles move at the right angles to the direction of the waves. However liquids can not support shear stresses and therefore S waves can not propagate through them.
In transverse waves, particles move in a parallel & perpendicular direction relative to the direction of energy transport.
