How do data seismic waves indicate that earths outer core is liquid?
Because since secondary waves cannot pass through liquids or solids, and the waves can't pass thruogh the outer core than that means that the outer core is not soild.
Which conclusion based on the analysis of seismic data supports the inference that earths outer core is liquid?
there are convection currents in the upper core.
How have scientist determined that the outer core of earth is liquid?
Scientists have determined that the outer core of Earth is liquid through seismic wave analysis. By studying the behavior of seismic waves as they pass through the Earth, scientists have found that S-waves are unable to travel through the outer core, indicating that it is liquid. This information has been crucial in our understanding of Earth's structure and dynamics.
Does not pass through earth's liquid outer core?
S-waves do not pass through Earth's liquid outer core because liquids cannot support the shear stress needed for these waves to propagate. This property helps scientists to understand the composition of Earth's layers by observing which seismic waves are transmitted or blocked.
What waves are refracted and what waves are absorbed by earth's outer core?
The sudden density change from the lower mantle to the outer core causes P-waves (compression or longitudinal waves) to be refracted and S-waves (shear or transverse waves) to be absorbed as the outer core is liquid and so cannot support the propagation of S-waves.
How do you know earths outer core is liquid?
Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
Shear waves will not pass through the?
Shear waves will not pass through the outer core of the Earth due to its liquid state. This is known as the "shadow zone" where S-waves are absorbed or refracted. This phenomenon was instrumental in providing evidence for the existence of the Earth's outer core.
How do data seismic waves indicate that earths outer core is liquid?
Because since secondary waves cannot pass through liquids or solids, and the waves can't pass thruogh the outer core than that means that the outer core is not soild.
Can secondary waves travel through the center of the earth?
No, because to reach the center of the Earth, they need to pass through the outer core. Secondary waves, or S-waves, can't pass through liquids, such as the liquid outer core, so they can't thus even reach the center of the Earth.
Why can't s waves pass trough the earth's core while p waves can?
This is because the Outer Core is liquid, and we know from experiments that S-waves cannot travel through liquids. If they could pass through the outer core, they could pass through the Inner, but they are absorbed by the first barrier, at the Gutenberg Discontinuity.
Which conclusion based on the analysis of seismic data supports the inference that earths outer core is liquid?
there are convection currents in the upper core.
What happens to seismic waves when they pass through the liquid outer core?
There are two types of waves. There are S waves (sheer waves) and P waves (compressional waves). The S waves won't travel through the outer core because it's a liquid, but the P waves will go through it and continue going through the inner core as well.
Could Geologists concluded that the outer core was liquid because p waves could not travel through it?
Yes, geologists determined that the outer core is liquid because P-waves cannot travel through it and instead undergo a shadow zone. P-waves can only pass through solid material, so the inability for P-waves to travel through the outer core indicates that it is in a liquid state.
How have scientist determined that the outer core of earth is liquid?
Scientists have determined that the outer core of Earth is liquid through seismic wave analysis. By studying the behavior of seismic waves as they pass through the Earth, scientists have found that S-waves are unable to travel through the outer core, indicating that it is liquid. This information has been crucial in our understanding of Earth's structure and dynamics.
Which type of seismic wave can only pass through earths mantle?
There is no seismic wave that can only pass through the Earth's mantle. However S-waves can not travel through earth's outer core because it is a liquid.
Does not pass through earth's liquid outer core?
S-waves do not pass through Earth's liquid outer core because liquids cannot support the shear stress needed for these waves to propagate. This property helps scientists to understand the composition of Earth's layers by observing which seismic waves are transmitted or blocked.
How Richard oldham discover that outer core of the earth was liquid?
Richard Oldham discovered that the outer core of the Earth was liquid through the analysis of seismic waves. He observed that certain seismic waves would not pass through the Earth's outer core, indicating it was a liquid layer that blocked those waves. This discovery revolutionized our understanding of the Earth's internal structure.
