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.
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.
What type of waves do earthquakes transmit?
Earthquakes transmit seismic waves, which are vibrations that travel through the Earth's crust and are responsible for the shaking felt during an earthquake. There are two main types of seismic waves: body waves (P-waves and S-waves) that travel through the Earth's interior, and surface waves that travel along the Earth's surface.
What do earthquakes waves transmit?
Seismic waves (like all waves) transmit energy.
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.
Which type of waves can travel through earth's outer cores?
Primary waves ( P-waves) can travel through earth's outer core.
What was assumed of the inner core as to how it transmitted waves?
We do not see shear (S) waves passing through the outer core. Because liquids can not be sheared, we infer that the outer core is molten. We do, however, see waves that travel through the outer core as P waves, and then transform into S waves as they go through the inner core. Because the inner core does transmit shear energy, we assume it is solid.

The study of how seismic waves change as they travel through the EARTH HAS REVEALED?
Earth's outer core is liquid because S-waves are not transmitted through this layer
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 satallites transmit sound waves to Earth?
Because you are in space. If you try calling someone in space, he or she wouldn't hear you.

What earth layer are s waves not transmitted?
S waves are not transmitted through the Earth's outer core because it is liquid, and S waves cannot travel through liquids. This creates a shadow zone on the opposite side of the Earth from an earthquake where S waves are not detected.
What is a body wave that does not penetrate the earth's core?
A body wave that does not penetrate the Earth's core is a compressional wave or P-wave. P-waves travel through the Earth by compressing and expanding the material they pass through, but they do not travel through the outer core because the outer core is liquid.
