In shadow zone, seismograph does not record signals. For P-wave it is b/w 104-145 degress.These earthquake waves exhibit same properties as other waves like reflection, refraction etc.As core has denser matter so P-waves will bend inward and hences they will form a shadow zone. S-waves don't pass through liquid phase, core. So, shadow zone is larger here.

∙ 9y agoThe shadow zone refers to an area of earth that does not receive direct P waves from earthquakes. It is the result of S waves being stopped entirely by the liquid core and P waves being bent by the core.

An s-wave shadow zone is formed as seismic waves travel through the Earth's body. Which of the following statements does this s-wave shadow zone indicate?
For earth science what evidence do we have that earth's outer core is molten?
This knowledge is based on the behavior of seismic waves, particularly the behavior of P-waves and S-waves. S-waves are unable to travel through liquids, and this particular wave trait indicates a boundary between the solid mantle and the liquid outer core. As S-Waves do not propagate through the outer core a "shadow" zone is created on the other side of the earth from the source of seismic waves. In this zone no S-waves are detected. The boundary between the inner core and outer core is also detected by a difference in velocities of P-waves. The Earth's magnetic field also originates in the liquid outer core by the movement and currents of molten metal in this layer.
What term is used to indicate the region where no earthquake waves reach Earth's surface?
seismic zone
Where are there no P waves or S waves?
Shadow zone
Why do S waves not come to the surface beyond the shadow zone?
S waves dont even reach the shadow zone because they are unable to penetrate the outer core. They are basically stopped by the shadow zone.
What is the band around the earth were seismic waves are not detected?
Shadow Zone
What is the band around the earth where seismic waves are not detected?
Shadow Zone
An area where no direct seismic waves from a particular earthquake can be detected?
shadow zone
What is the wide belt in which no seismic waves are received?
shadow zone
What is the name of the area where no seismic waves occur in an earthquake?
Shadow zone
The shadow zone exists due to the of seismic waves?
refraction refraction
What does the shadow zone have to do with earthquakes?
This is caused by the density variations in the earth which cause the velocity of seismic waves to change as they move between them which in turn causes refraction of the waves. Further to this, the earth's outer core is a liquid which prevents seismic S-waves from travelling through it. This leads to a zone on the opposite side of the earth from an earthquake where S-waves are not detected.
Area where no direct seismic waves from a particular earthquake can be traced?
This, would be knows as the Shadow Zone.
What is the area where no seismic waves are detected called?
It is called the shadow zone, an area at an angle of between 104° and 140° from the axis of the epicenter, where the earth's liquid outer core has refracted the P-waves away from the direct line of travel.
Why do shadow zones exist?
P-waves refract as they travel through Earth so do not rach all other pars of the earth's surface. Also S-waves can't travel through liquids and so can't pass through the earth's outer core which also causes a shadow zone.
What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
