The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but
surface waves can only move along the surface of the planet like ripples on water
.
Do surface waves travel faster than body waves?
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids.
Surface waves are the slowest
, but they do the most damage in an earthquake.
What is the main difference between surface waves and body waves quizlet?
How do surface waves differ from body waves?
Body waves travel through earths interior while surface waves travel along the earths surface
.
Why do body waves travel differently?
P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because
the interior of the Earth does not react the same way to both of them
. P-waves are compression waves that apply a force in the direction of propagation.
Which is stronger the body or surface waves?
Surface waves
travel more slowly through Earth material at the planet’s surface and are predominantly lower frequency than body waves. They are easily distinguished on a seismogram. Shallow earthquakes produce stronger surface waves; the strength of the surface waves are reduced in deeper earthquakes.
What do surface waves do?
Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They
cause the most surface destruction
.
What is the difference between body waves and surface waves and between P waves and S waves?
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
P-waves are compression waves. They can propagate in solid or liquid material. S-waves are shear waves
.
Which statement correctly describes the main difference between body waves and surface waves?
Which statement explains the difference between body (P and S) waves and surface waves?
Surface waves only move across the surface and body waves move through the inner layers
.
Why surface waves cause more damage than the body waves?
Surface waves – By a property called dispersion, surface waves of different wave lengths travel at different velocities. It is the surface waves which cause most property damage because
surface waves produce more ground movement and travel more slowly, so they take longer to pass
.
What is one of the differences between body waves and surface waves?
Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water
. Earthquakes send out seismic energy as both body and surface waves.
Where do body waves and surface waves travel quizlet?
Body waves travel
within Earth, and surface waves travel along Earth’s surface
.
How do surface seismic waves differ from P waves and S waves quizlet?
What are the differences between P waves, S waves, and surface waves? P waves are the fastest and have the lowest amplitudes; S waves are the second fastest and have the second lowest amplitudes;
surface waves are the slowest and have the highest amplitudes
.
Which wave travels faster?
Light waves
travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.
Which waves move the fastest?
P-waves, or primary waves
, are the fastest moving type of wave and the first detected by seismographs. They are also called compressional or longitudinal waves, and push and pull the ground in the direction the wave is traveling.
How do waves behave differently in Earth’s interior?
The waves are refracted as they travel through the Earth due to a change in density of the medium
. This causes the waves to travel in curved paths. When the waves cross the boundary between two different layers, there is a sudden change in direction due to refraction.
How far can surface waves travel?
At Earth’s surface, P waves travel somewhere
between 5 and 8 kilometers per second
(3.1 and 5 miles per second). Deeper within the planet, where pressures are higher and material is typically more dense, these waves can travel up to 13 kilometers per second (8.1 miles per second).
Are surface waves transverse or longitudinal?
While waves that travel within the depths of the ocean are longitudinal waves, the waves that travel along the surface of the oceans are referred to as surface waves. A surface wave is a wave in which particles of the medium undergo a circular motion. Surface waves are
neither longitudinal nor transverse
.
Can surface waves travel through liquids?
When they reach the surface they cause horizontal shaking. Liquids don’t have any shear strength and so
a shear wave cannot propagate through a liquid
. Think of a solid material, like a rock. That rock is made up of atoms and molecules bound to each other.
What is the difference between the sound waves and the waves on the surface of the water body?
For water waves, the disturbance is in the surface of the water, perhaps created by a rock thrown into a pond or by a swimmer splashing the surface repeatedly. For sound waves, the disturbance is a change in air pressure, perhaps created by the oscillating cone inside a speaker.
How are primary and secondary waves different from each other?
Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A).
Secondary waves, or S waves, are slower than P waves
.
