Seismic waves travel faster when they travel through the core
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.

the inner core
Yes the refraction path of the p-wave tells us that the earths inner core is solid.
The immense pressure from the layers outside of the inner core.
It is said that the crust and the inner core are to be solid.
The solid inner and liquid outer core.
The mantle! I remember learning this in geography :)
An alloy of solid nickel and iron, mostly.

The inner core Is solid and the outer core in liquid
