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.
there are convection currents in the upper core.
They go faster through the inner core than the liquid outer core
So far as science can deduce, it must be a solid.
seismic waves travel slowly trough
Seismic waves generated by earthquakes provide crucial insights into Earth's interior by revealing how these waves travel through different materials. By analyzing the speed and behavior of seismic waves, scientists can infer the composition and state of various layers, such as the crust, mantle, and core. For instance, the reflection and refraction of these waves indicate transitions between solid and liquid layers, helping to confirm the existence of the Earth's liquid outer core. This method has significantly advanced our understanding of Earth's internal structure and dynamics.

hot liquid layer
No it is liquid
The liquid layer of the Earth's core is called the outer core.
There is no seismic wave that can only pass through the Earth's mantle. However S-waves can not travel through earth's outer core because it is a liquid.
The solid inner and liquid outer core.
