When P waves and S waves reach Earth’s surface
, they can create surface waves. A surface wave is a combination of a longitudinal wave
How is a surface wave formed?
Wind-driven waves, or surface waves, are created
by the friction between wind and surface water
. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast.
What is a surface wave quizlet?
surface waves.
seismic waves that move rock particles in a backward, rolling motion and a sideways swaying motion
. strongest waves, but slowest.
Which is true about surface waves quizlet?
What is a surface wave?
Surface waves move faster than P waves and S waves, but produce severe ground movements
. Surface waves can make the ground roll like ocean waves or even shake buildings. Surface waves produce the largest disturbance on the seismogram.
What creates a seismic wave quizlet?
Seismic waves – what is the full definition?
vibrations that travel through Earth carrying the energy released during an earthquake
. Three types of seismic waves are P waves, S waves, and surface waves.
Why do surface waves cause the most damage?
Surface waves are slower than body waves. … 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 the motion of a P waves and S wave surface waves quizlet?
P waves- compress and expand the ground like an accordian
. Travel through both solids and liquids. S waves- vibrate from side to side as well as up and down. They shake the ground back and forth and when they reach the surface they shake structures violently.
Why do surface waves cause so much destruction quizlet?
They move along the Earth’s surface and mostly affect only the upper few kilometers of the Earth’s crust. Surface waves are generated by the interaction of the P- and S-waves with the surface and internal layers of the Earth. Surface waves cause the most destruction
because they make the ground roll
.
Where do P waves travel the fastest quizlet?
P-WAVES travel fastest
through rock
. P-waves can travel in any kind of material( liquid , solid). S waves travel slower through rock S-waves cannot travel through the outer core
What happens to the medium when a wave moves quizlet?
What happens to the medium when a wave moves?
It moves up and down or back and forth, but it does not move forward with the wave
. Mechanical waves
Where do seismic waves travel quizlet?
How do seismic waves travel? They move
outward from the focus in all directions
. What is the epicenter? The point on Earth’s surface directly above the earthquake’s focus.
What is the resulting of a surface wave?
The correct answer is (b)
Circular
. The resulting direction of a surface wave will be circular. 1. Longitudinal waves
What is the two types of seismic waves?
There are several different kinds of seismic waves, and they all move in different ways. 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.
What is a real life example of a surface wave?
In physics, a surface wave is a mechanical wave
Which surface wave is the most destructive?
Of the two types of surface waves,
the L-waves
are the most destructive. They can literally move the ground beneath a building faster than the building itself can respond, effectively shearing the base off of the rest of the building.
What type of destruction do surface waves cause?
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.
