Yes, P-waves (primary waves) can pass through the liquid outer core of the Earth. Unlike S-waves (secondary waves), which cannot travel through liquids, P-waves are compressional waves that can move through both solids and liquids. As a result, they are able to propagate through the outer core, allowing seismic waves to be detected on the other side of the Earth. This characteristic helps scientists infer the composition and state of the Earth's internal layers.

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 wave Does not pass through earths liquid outer core?
S-waves, or shear waves, do not pass through Earth's liquid outer core. Unlike P-waves (primary waves), which are compressional and can travel through both solids and liquids, S-waves can only move through solids. This inability to traverse the liquid outer core provides crucial evidence for the Earth's internal structure.
Earth and outer core will not transmit S waves because it is made of?
Earth's outer core is composed primarily of liquid iron and nickel, which cannot transmit S waves because these waves require a solid medium to propagate. When S waves encounter the liquid outer core, they are absorbed rather than transmitted, resulting in a shadow zone where no S waves are detected. This property of the outer core provides crucial evidence for its liquid state.
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.
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.

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.
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.
What happens when s waves hit the outer core of earth?
S-waves cannot travel through the liquid outer core because it cannot support shear stress. Instead, they are either absorbed or reflected when they reach the outer core boundary, causing a shadow zone on the opposite side of the Earth from the earthquake where these waves are not detected.
What waves are refracted and what waves are absorbed by earth's outer core?

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 part of earth core is liquid?
Scientists suspect that the outer core is liquid because of its interaction with seismic waves. Actually, only one segment of inner earth is theorized to be liquid. This segment is known as the outer core
What area of earth is not affected by both p and s waves?
The liquid outer core of the Earth's interior refracts p-waves at the boundary with the mantle, and does not carry s-waves.
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.
For earth science what evidence do we have that earth's outer core is molten?
This knowledge is based on the behavior of seismic waves, particularly the behavior of P-waves and S-waves. S-waves are unable to travel through liquids, and this particular wave trait indicates a boundary between the solid mantle and the liquid outer core. As S-Waves do not propagate through the outer core a "shadow" zone is created on the other side of the earth from the source of seismic waves. In this zone no S-waves are detected. The boundary between the inner core and outer core is also detected by a difference in velocities of P-waves. The Earth's magnetic field also originates in the liquid outer core by the movement and currents of molten metal in this layer.
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
