Because it has been proven that the outer layer is made of liquid and secondary waves do not move through liquid ^~^
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
s waves cant travel through it
They go faster through the inner core than the liquid outer core.
Firstly, there are 3 types of seismic waves. Long Waves, Primary Waves(Longitudinal) and Secondary Waves(Transverse). Long Waves travel quickly along the Earth's crust, the thin outer layer. Primary Waves are longitudinal waves, they can travel both through solids andliquids, so they travel through the crust, the mantle, and the outer core (note that they refract through each layer, as each layer has a different density. Secondary Waves are transverse waves, they can only travel through solids, so they go through the inner and outer mantles, and curve away from the cores.
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.
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.
Secondary waves, also known as S-waves, do not travel through the outer core of the Earth due to its liquid state. S-waves can only propagate through solid materials.
the outer core
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.
Liquid outer core
S-Waves, or shear waves cannot travel through the liquid outer core because liquids have no shear and therefore shear waves cannot propagate through them http://en.wikipedia.org/wiki/S-wave
Surface waves, also known as Love and Rayleigh waves, do not travel through the core of the Earth. These waves move along the surface of the Earth and are responsible for the most destruction during an earthquake.
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.
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.
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.
there are convection currents in the upper core.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
