How do S and P waves move through the Earth? What happens to them as they move through the layers?
S-waves, also known as shear waves, move through the Earth by causing particles to move perpendicular to the direction of wave propagation. They travel slower than P-waves and cannot penetrate through liquids. As S-waves encounter the various layers of the Earth, their motion can be affected. For instance, when S-waves encounter the outer core, which is liquid, they cannot pass through it and are thus blocked. This phenomenon is known as the S-wave shadow zone.
On the other hand, P-waves, also called primary waves or compressional waves, move through the Earth by causing particles to move in the same direction as the wave propagation. P-waves are capable of passing through solids, liquids, and gases. As P-waves encounter different layers within the Earth, they can change direction or refract due to differences in the density and composition of the materials they pass through. This refraction of P-waves is responsible for the detection and mapping of the Earth's internal structure.

Which stations will record fewer waves than the others based on their locations?
Stations located farther away from the earthquake epicenter will record fewer waves compared to stations located closer to the epicenter. As seismic waves travel through the Earth, their intensity reduces with distance, resulting in fewer waves being recorded at more distant stations. Therefore, stations that are further away from the earthquake source will generally record fewer waves.

Based on the information provided, it is not possible to determine which specific stations will record fewer waves than the others. The answer depends on the actual locations of the stations in relation to the earthquake epicenter. Different distances and angles from the epicenter can result in variations in the number and intensity of waves recorded at each station.

The accurate statement about earthquakes is: "Seismic waves change speed when density changes in the Earth's layers." Seismic waves do indeed change speed when they encounter different densities within the Earth's layers, which can affect their direction, refraction, and reflection. This property of seismic waves is crucial for understanding the internal structure of the Earth.
