Is it true or false as s waves move through the ground they cause it to compress and then expand?
False. S waves (secondary waves) move through the ground by shearing the rock particles side to side, creating a horizontal motion that is perpendicular to their direction of travel. This shearing motion can cause the ground to move in a wave-like pattern, but not compress and then expand as with compressional waves (P waves).
What are the fastest waves that compress and expand the ground like an accordion?
The fastest waves that compress and expand the ground like an accordion are primary waves (P-waves). These seismic waves are the first to arrive after an earthquake and travel through solids, liquids, and gases. They cause particles in the ground to move in the same direction as the wave itself, resulting in the compressional and expansion effects.
2 examples of longditudinal waves?
Sound waves in air or water are longitudinal waves where the particles vibrate in the same direction as the wave travels. Seismic waves generated by earthquakes are longitudinal waves that travel through the Earth's interior, causing the ground to compress and expand in the direction of wave propagation.
If primary waves and secondary wave move outwards what will happen?
Primary waves (P-waves) are compressional waves that travel faster through the interior of the Earth, followed by secondary waves (S-waves) which are transverse waves. As P-waves pass through a medium, they compress and expand the material in the direction of propagation. S-waves are slower, causing particles to move perpendicular to the direction of wave travel. The combination of these two waves helps seismologists to locate the epicenter of an earthquake and study the Earth's interior structure.
How do sound waves differ from other types of waves, and what characteristic defines them as longitudinal waves?
Sound waves are a type of longitudinal wave, which means that the particles in the medium vibrate in the same direction as the wave travels. This is different from transverse waves, where the particles move perpendicular to the direction of the wave. Sound waves are defined by their ability to travel through a medium, such as air or water, by causing the particles in the medium to compress and expand as the wave passes through.
What body waves consist?
Body waves consist of two main types: primary waves (P-waves) and secondary waves (S-waves). P-waves are longitudinal waves that compress and expand the material they travel through, moving faster than S-waves. S-waves are transverse waves that move perpendicular to the direction of wave propagation, and they can only travel through solids. Together, these waves provide essential information about the Earth's interior during seismic events.
What best describes the movement of P waves?
P waves, or primary waves, are a type of seismic wave that compress and expand the material they travel through, similar to sound waves. They move through solids, liquids, and gases, with their movement characterized by alternating compressions and rarefactions in the direction of wave propagation. This longitudinal motion allows P waves to travel faster than other seismic waves, making them the first to be detected by seismographs during an earthquake.

How do different types of seismic waves affect the rocks through which they travel?
Seismic waves travel through rocks in various ways, primarily categorized as primary (P) waves, secondary (S) waves, and surface waves. P waves are compressional waves that compress and expand the material, causing it to move back and forth in the direction of wave propagation, which can lead to elastic deformation. S waves, being shear waves, move rocks perpendicular to their direction of travel, causing more complex movements and often resulting in shear stress that can lead to fractures or faults. Surface waves, which travel along the Earth's surface, typically cause the most damage, generating rolling or swaying motions that can significantly weaken structures and disturb the ground.
