I think the outer core
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.
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.
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 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.
The Earth's iron core doesn't melt despite its extremely high temperature and pressure because the pressure from the weight of all the material above it raises its melting temperature significantly. This results in the iron core remaining solid even at temperatures well above its melting point.
Molten iron is primarily found in the outer core of the Earth, which is a layer of liquid iron and nickel that surrounds the solid inner core. The high temperatures and pressures in the outer core keep the iron in a liquid state.
The Earth's inner core primarily consists of iron and nickel. It is solid despite the extreme temperatures due to the immense pressure at that depth, which prevents the iron and nickel from melting. This solid inner core is surrounded by a liquid outer core, which also contains these elements.
1535 degree melting of iron
The earth's inner core is primarily made up of iron. The inner core is under great pressure: around 350 gigapascals or 3.5 million atmospheres. At such pressures, the melting point of iron is much higher than the normal 1811 K. In fact, the melting point of iron, at the boundary between the inner and outer core is around 6,200 K, well above the 5,700 K to be found there.
The Earth's magnetic field is created by the rotation of its dense core, which is mostly iron and nickel but with heavy radioactive elements as well. The inner core is above the melting temperature of the metals, but is kept solid by gravitational pressure. The outer core is a viscous liquid metal.
