The amount of pressure overcomes the material's disposition to melting at high temperature. It solidifies.
The immense pressure from the layers outside of the inner core.
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.
The densest layer of Earth's compositional layers is the inner core. Composed primarily of iron and nickel, it has a solid state due to the immense pressure at Earth's center, despite the high temperatures. The inner core is surrounded by the outer core, which is liquid and also primarily made of iron and nickel, but the solid inner core is denser than the surrounding layers.
The Earth's inner core remains solid due to the immense pressure that exists at the center of the planet. This pressure is so high that it prevents the iron and nickel in the inner core from melting, despite the high temperatures. Additionally, the inner core's solid state is maintained by the slow cooling and freezing process that occurs as heat escapes from the core to the outer layers of the Earth.
The inner core of Earth is solid due to the immense pressure from the layers above it. This pressure prevents the iron and nickel in the inner core from melting despite the high temperatures. Additionally, the solidification process helps to release some of the heat generated by radioactive decay in the core.

Outer Core, Inner Core, Mantle, Crust
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.
Crust, mantle, and inner core.
The layers of the Earth in order from lowest pressure to greatest pressure are the crust, mantle, outer core, and inner core. The inner core experiences the highest pressure due to the weight of all the layers above it.
I just studied them. They are: Crust, Mantle, Outer Core and Inner Core

Inner core (probably solid); outer core (probably liquid); mantle, crust.
