What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
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.
An area where no direct seismic waves from a particular earthquake can be detected?
shadow zone
What is the name of the area where no seismic waves occur in an earthquake?
Shadow zone
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 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 do you call seismic waves that are transmitted along the outside of the earth?
surface waves
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.
What do we call earthquake waves?
Earthquake waves are called seismic waves. There are two main types of seismic waves: body waves, which travel through the Earth's interior, and surface waves, which travel along the Earth's surface. These waves are responsible for the shaking and damage caused by earthquakes.
What term is used to indicate the region where no earthquake waves reach Earth's surface?
Shadow zone is the term used to indicate the region where no earthquake waves reach Earth's surface. This area occurs beyond 105 degrees from the epicenter of an earthquake.
Is the shadow zone always inthe same location on earth?
No, the shadow zone is not always in the same location on Earth. The shadow zone refers to regions where seismic waves, particularly P-waves, do not arrive due to the Earth's structure, including its core and mantle. As seismic waves travel, their paths can be affected by various geological factors, and the location of the shadow zone will vary depending on the position of the earthquake and the Earth's rotation. Thus, the shadow zone shifts with each seismic event.
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.
