What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
What can be used to map the deep interior of the earth?
The deep interior of the Earth can be mapped using seismic waves. Natural earthquakes produce seismic signals which penetrate the Earth. Timing the arrival of these waves at various sites round the world, gives indication of the shape and the wave velocity in the Earths interior. Rather similar to the way a CAT scan can reveal the interior of a person.
What is seismic shaking-?
"Seismic" refers to an earthquake, so seismic shaking is the shaking motion of the earth (and things on it) caused by an earthquake. There are different waves that emanate from the hypocenter, or point of origin.
What is the main thing scientist observe in order to learn about the makeup of the earth's interior?
Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
Does a seismic wave require a medium?
Yes, earth is the medium
Which area indicates a dramatic decrease and material density inside the earth?
The transition from the outer core to the lower mantle, known as the core-mantle boundary, is a region where there is a dramatic decrease in material density inside the Earth. This boundary is characterized by a significant change in the physical properties of the materials, such as a decrease in density and an increase in seismic wave velocity.
Does the Moho barrier separate the earth's crust and mantle?
Yes. It is called the Mohorovicic Discontinuity, where seismic waves increase in velocity.
If radius of the earth is doubled then value of critical velocity becomes what?
The question cannot be answered because the question provides no information on the mass of the "new" earth. Also, if it is a more massive earth then it is more likely to have a denser atmosphere.
What is Monorovicicdiscontinuity?
It is the boundary between the earth's crust and mantle, across which there is a sudden change in the velocity of seismic waves Often shortened to Moho
The seismic discontinuity at the base of the crust is known as?
The seismic discontinuity at the base of the crust is known as the Mohorovičić discontinuity, or Moho for short. It marks the boundary between the Earth's crust and the underlying mantle, where seismic waves experience a sudden change in velocity.
Which are indicates a dramatic decrease in material density inside the earth?
Seismic waves traveling through the Earth have indicated a decrease in material density in the mantle transition zone. Another indicator is the presence of magma chambers near the Earth's surface, suggesting a decrease in density as material rises from the mantle. Additionally, the behavior of gravity anomalies can also suggest a decrease in material density inside the Earth.
Who discovered the crust mantle seismic discontinuity?
The crust-mantle seismic discontinuity was discovered by Yugoslav seismologist, Andrija Mohorovičić, in 1909 through his observation of seismic waves. This discontinuity marks the boundary between Earth's crust and mantle, characterized by a sudden increase in seismic wave velocity.
How did scientists discover Earth's mantle?
they drill into the earth but not all the way obviously and the predict that there is a mantel by volcanoes my teacher use to drill into the earth as a scientist but then returned to teaching ans2. The interior of the Earth may be inferred by studying seismic waves at various points from a given earthquake. From this the depth of various layers and their acoustic velocity may be determined.
What does seismic?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
Which of the following increase with depth within Earth's interior?
Pressure and temperature increase with depth within Earth's interior, while density and seismic wave velocity also tend to increase.
The velocities of seismic waves traveling from earthquake foci?
The velocities of seismic waves traveling from earthquake foci depend on the type of waves and the properties of the material they travel through. For example, P waves are faster than S waves because they are compressional waves that can travel through both solids and liquids. The speed of seismic waves can also give information about the nature and structure of the Earth's interior.
