P Waves
What else can I help you with?
Which seismic waves compress and expand rocks in the direction the wave travel?
P waves
P waves?
seismic waves that puch copmpress and pull in the diection thta waves travel
Waves that compress and expand in the direction that the waves travel?
Longitudinal waves.
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.
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.
Which direction do Seismic waves travel?
in all directions
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.
Can a p wave travel through gas?
Yes, a P-wave can travel through gas. P-waves are seismic waves that are the fastest and can travel through solids, liquids, and gases. They compress and expand the material they travel through, which allows them to propagate through gases as well.
S waves?
seismic waves thta shakes particles at right angles to the dircetion that they travel
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).
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.
How do you know waves transfer energy in the direction of the travel of wave?
seismic waves travel in all directions. the reason we know is because of earthquakes.
