What waves squeeze and stretch material in the same direction as the wave is moving?
P waves, also called compressional or longitudinal waves, give the transmitting medium—whether liquid, solid, or gas—a back-and-forth motion in the direction of the path of propagation, thus stretching or compressing the medium as the wave passes any one point in a manner similar to that of sound waves in air.
Which wave move in two directions as they pass through rock?
In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
What type of seismic wave causes rock to move both up and down and from side to side?
P-waves are the fastest type of seismic wave. As P-waves travel, the surrounding rock is repeatedly compressed and then stretched. S-waves arrive after P-waves because they travel more slowly. The rock is shifted up and down or side to side as the wave travels through it.
What kind of waves cause particles in rocks to move at right angles to the direction of the wave?
Chapter 11 Vocabulary – Earthquakes
| A | B |
|---|---|
| Secondary Wave | Seismic wave that moves rock particles at right angles to the direction of the wave. (shearing waves) |
| Epicenter | Point on Earth’s surface directly above an earthquake’s focus. |
What’s the difference between longitudinal and transverse waves?
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Are push pull waves on a slinky transverse or longitudinal?
Longitudinal waves are often demonstrated by pushing and pulling a stretched slinky spring. In the diagram, the compressions move from left to right and energy is transferred from left to right.
Which type of seismic wave pulls rocks in the same direction of the wave?
P body wave
A P body wave (primary body wave) is a compressional (longitudinal) wave that induces the particles in the rock to vibrate back and forth in the same direction the wave moves. P. waves move at speeds up to 15,000 miles per hour (7 kilometers/second) (Figure 1 ).
Which kind of wave has a push pull motion?
P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave is moves in; it is the direction that the energy is traveling in, sometimes called the “direction of wave propagation.”
Which of the following types of seismic waves causes rock to move in the same direction as the wave movement?
A P body wave (primary body wave) is a compressional (longitudinal) wave that induces the particles in the rock to vibrate back and forth in the same direction the wave moves.
What causes rock to move?
Seismic wave that squeezes and pulls rocks in the same direction that the wave travels, causing rock particles to move back and forth.
What is similar between transverse and longitudinal waves?
For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
How do seismic waves move the ground?
Seismic wave that causes rock particles to move at right angles to the direction of the wave. surface wave Seismic wave that moves in two directions as it passes through rocks, causing the ground to move both up and down and from side to side.
What are primary and secondary waves in geology?
primary wave. Seismic wave that squeezes and pulls rocks in the same direction that the wave travels, causing rock particles to move back and forth. secondary wave. Seismic wave that causes rock particles to move at right angles to the direction of the wave.
What is the difference between surface waves and P waves?
(t/f) Surface waves are the first to arrive at a seismic facility. (t/f) P-waves are bent when they strike the core. (t/f) On seismograms, seismic waves recorded from more distance facilities are closer together than those recorded from facilities close to the epicenter.
What causes the ground to move up and down?
Seismic wave that moves in two directions as it passes through rocks, causing the ground to move both up and down and from side to side. focus Point of the initial fault rupture where an earthquake originates that usually lies at least several kilometers beneath Earth’s surface.
