solid due to extreme pressure, even though it is composed of mostly iron and nickel.
The immense pressure from the layers outside of the inner core.
The amount of pressure overcomes the material's disposition to melting at high temperature. It solidifies.
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 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.

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 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.

The inner core is solid because of the immense pressure from the layers above it that compresses the iron and nickel present at high temperatures. This pressure causes the inner core to solidify despite the high temperatures.
The inner core of the Earth is completely solid due to the immense pressure from the layers above it, which prevents it from melting despite its high temperature.
The inner core of the Earth is solid due to the immense pressure exerted by the layers of rock and metal above it, which raises its melting point. The solid inner core is still extremely hot, but its high pressure keeps it in a solid state.
