I think the outer core
The high pressure at the center of the Earth keeps the inner core in a solid phase, despite the extreme temperatures. The pressure prevents the iron in the inner core from melting, maintaining its solid structure.

Iron and nickel are solid in the inner core due to the extremely high pressure and temperature conditions present there. The pressure is so intense that it keeps the iron and nickel in a solid state despite their high melting points.
The iron core of the Earth is solid because of the immense pressure and high temperatures deep within the planet, which prevent the iron from melting.
high pressure
The inner core of the Earth has a temperature higher than its melting point. Despite being made of solid iron and nickel, the immense pressure at the center of the Earth keeps it in a solid state even at temperatures above its melting point.
The temperature of the outer core is higher than its melting point. The outer core is mainly composed of liquid iron and nickel, which has a melting point higher than the temperature of the outer core due to the immense pressure at that depth.
The iron core of the earth is solid because the immense pressure near the center of the earth, due to gravity, keeps the iron in a solid state, even though it is hot.
The inner core of the Earth is kept from melting by the immense pressure exerted on it by the overlying layers of the Earth, such as the outer core and mantle. This pressure raises the melting point of the iron and nickel present in the inner core, preventing them from melting despite the high temperatures. Additionally, the inner core's solid state is also maintained by the heat generated by radioactive decay within the Earth.
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.
