Because it has been proven that the outer layer is made of liquid and secondary waves do not move through liquid ^~^

What body wave can't move through the liquid outer core?
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
What happens when p waves and S waves try to pass through the outer core?
s waves cant travel through it
How does earths solid inner core affect seismic waves?
They go faster through the inner core than the liquid outer core.
What are the differences between primary and secondary and seismic waves?
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.
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.
What type of seismic wave does not travel through the core?
Primary waves ( P-waves) can travel through earth's outer core.
What layer of Earth do Secondary waves NOT travel through?
Outer core and Mantle
Secondary waves can travel through all areas of the Earth except the?
the outer core
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 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.
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.
What stops secondary waves?
Liquid 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.
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 body wave can't move through the liquid outer core?
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
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.
Which type of waves can travel through earth's outer cores?
Primary waves ( P-waves) can travel through earth's outer core.
