Why do p waves seem to bend when they hit the outer core of the earth?

∙ 14y agoBecause the outer core and the mantle have different densities and pressures, and the wave behavior is dependent on these things.

How have scientist determined that the outer core of earth is liquid?
Because S-waves come to a complete stop in the outer core.
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.
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.
Does not pass through earth's liquid outer core?
S-Waves
What layer of Earth do Secondary waves NOT travel through?
Outer core and Mantle
Which type of waves can travel through earth's outer cores?
Primary waves ( P-waves) can travel through earth's outer core.
What earth layer are s waves not transmitted?
S waves can not travel through liquids, the outer core is a liquid, so the S waves can not travel through the outer core. You can also determine that since the outer core is all around the inner core, that the S waves can no travel through the inner core as well.

Shear waves will not pass through the molten outer core of the Earth.

Outer core and Mantle
What happens when s waves hit the outer core of earth?
Because the Earth's core is liquid; S-waves can't travel through liquid.
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.
Do S waves travel through earth's inner core?
While S waves (shear waves) can travel through earth's solid inner core, they cannot travel through earth's liquid outer core, which surrounds the inner core.So, unless the S waves originated inside the inner core (which seems unlikely) there are no S waves traveling through earth's inner core.
How does Earth solid core affect seismic waves?
They go faster through the inner core than the liquid outer core.
