there are 3 types of shock waves produced by an earthquake:
the P waves which is known as the (primary or compression) waves are the first to arrive at the recording station, p waves are formed when matter in the rocks is pushed together by the earth's movement. they can travel through solids and liquids.
the S waves which is known as the (secondary )waves are the second waves to arrive at the recording station. this waves are also called the shear waves. these waves are formed by the sideways motion of matter, it can only travel through solids.

Secondary waves are also known as shear waves and primary waves are also known as pressure waves.
Primary (P) waves : Primary waves, the fastest wave sent , come from the focus not the epicenter. (S) waves : Secondary waves, the second fastest wave sent out by an earthquake, it comes from the focus also.
P-waves stand for primary waves, but a good trick is to think of the P as standing for pressure, because P waves are compression waves. S-wave stands for secondary wave, but the trick is to think of the S as standing for shear wave. This is because S-waves move in a shearing (side to side) motion. The means that S waves cannot travel through liquid, and also travel slower than P-waves.
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
For P waves, the two descriptive words are Primary (or compressional) waves, while for S waves, the two words are Secondary (or shear) waves.
P waves arrive first.
seismic waves
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
P-waves and S-waves. P waves are known as Primary waves as they have a high velocity and so are recorded at seismometer stations before Secondary or S-waves. P waves may also be known as pressure waves as they are in fact compression or longitudinal waves. S-waves may also be known as shear waves as they are transverse waves.
Primary (P) waves : Primary waves, the fastest wave sent , come from the focus not the epicenter. (S) waves : Secondary waves, the second fastest wave sent out by an earthquake, it comes from the focus also.
P-waves are longitudinal and S-waves are transverse waves.
shear waves
P and S waves are body waves.
seismic waves actually the correct answer is S waves. trust me if you put seismic waves it will be wrong
P-waves stand for primary waves, but a good trick is to think of the P as standing for pressure, because P waves are compression waves. S-wave stands for secondary wave, but the trick is to think of the S as standing for shear wave. This is because S-waves move in a shearing (side to side) motion. The means that S waves cannot travel through liquid, and also travel slower than P-waves.
Waves produced by earthquakes are called seismic waves. These waves can be further categorized into primary (P-waves), secondary (S-waves), and surface waves.
P waves arrive before S waves during an earthquake, as P waves are faster and can travel through solid rock, while S waves can only travel through solids and are slower. This difference in arrival time can be used to determine the distance of the earthquake epicenter from the seismograph station.
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
