Earth's solid inner core influences seismic waves by acting as a boundary that alters their speed and path. P-waves (primary waves) can travel through both solid and liquid, allowing them to pass through the inner core, while S-waves (secondary waves), which can only move through solids, are reflected at the boundary between the liquid outer core and the solid inner core. This interaction creates distinct shadow zones where S-waves are absent, providing crucial information about the Earth's internal structure. Additionally, the properties of the inner core can lead to variations in wave velocity, aiding scientists in understanding the Earth's composition and dynamics.
The immense pressure from the layers outside of the inner core.
The mantle! I remember learning this in geography :)
An alloy of solid nickel and iron, mostly.
So far as science can deduce, it must be a solid.
Earths inner core is solid due to the extreme pressure from the weight of the layers above it, which exceeds the melting point of the iron and nickel it is composed of. This pressure prevents the core from melting despite its high temperature.

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 inner core Is solid and the outer core in liquid
The Inner Core is a liquid. Outer core: solid mantel: inbetween crust: solid
Both! The outer core is in a liquid state and the inner core is a solid. Both the inner and outer core are formed mainly of iron and nickel.
