What is the band around the earth were seismic waves are not detected?
The band around the Earth where seismic waves are not detected is called the "shadow zone." This region exists between 105 to 140 degrees from the epicenter of an earthquake and is caused by the refraction of seismic waves within the Earth's core. It is divided into two main parts, the P-wave shadow zone and the S-wave shadow zone.
What is the band around the earth where seismic waves are not detected?
The band around the Earth where seismic waves are not detected is known as the seismic shadow zone. It exists between 105 and 140 degrees away from the earthquake epicenter. Seismic waves are not detected in this region due to the refraction and reflection of waves in the Earth's interior layers.
What is the wide belt in which no seismic waves are received?
The region is known as a seismic shadow zone, located between 104 and 143 degrees from the epicenter of an earthquake. This area exists due to the core's properties refracting seismic waves away from it, causing minimal wave detection.
The shadow zone exists because?
sunlight blocks out S waves in certain regions.
What does the shadow zone tell scientists about Earths interior?
The shadow zone is an area on Earth's surface where no seismic waves are detected after an earthquake. This helps scientists understand the Earth's interior structure, as the absence of seismic waves in this zone indicates the presence of a liquid outer core that blocks the transmission of certain seismic waves.

What is the name of the area where no seismic waves occur in an earthquake?
Shadow zone
An area where no direct seismic waves from a particular earthquake can be detected?
shadow zone
Why do the shawdow zone exist?
The shadow zone exists because seismic waves from an earthquake are refracted by the Earth's core, causing a gap where no waves are detected on the opposite side of the Earth. This phenomenon occurs due to differences in the composition and density of the Earth's layers, which affect the speed and path of seismic waves.

This helps scientists understand the Earth's interior structure, as the absence of seismic waves in this zone indicates the presence of a liquid outer core that blocks the transmission of certain seismic waves.
Area where no direct seismic waves from a particular earthquake can be traced?
This, would be knows as the Shadow Zone.
Where are there no P waves or S waves?
In the Earth's outer core, which is composed of molten iron and nickel, seismic waves (P and S waves) are not able to travel through it due to its liquid state. This causes a shadow zone on the opposite side of the Earth from a seismic event, where P waves are completely deflected and S waves are not detected.
What is the shadow zone caused by?
The shadow zone is caused by the refraction of seismic waves in Earth's core. P and S waves are refracted (bent) as they travel through different layers of the Earth, leading to a region where they are not detected by seismographs.
What happens to the size of the shadow zone as the diameter of the liquid core increases?
As the diameter of the liquid core increases, the size of the shadow zone decreases. This is because the larger diameter allows for more refraction of seismic waves, leading to less complete shadowing of seismic waves at certain distances.
