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 Earth's core is mainly made of iron and nickel. The outer core is liquid, while the inner core is solid, due to high pressures and temperatures.
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 is solid due to the immense pressure from the surrounding layers of the Earth. The pressure is so intense that it keeps the iron and nickel in the inner core in a solid state despite the high temperatures.
The inner core of the Earth is solid because of the immense pressure it experiences due to the overlying layers. Despite the high temperatures, the pressure prevents the inner core from melting. The high pressure keeps the iron and nickel in the inner core in a solid state.

There are two parts of the core: Inner and Outer. The outer core is liquid, the inner solid. The inner core is solid due to the pressure exerted on it, despite the excessively high temperature.
The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.
The solid state of of the inner core is due to pressure caused by the weight of everything above it.
The solid state of of the inner core is due to pressure caused by the weight of everything above it.
In inner core is solid while the outer core is liquid. This is because the inner core, being deeper, is under more pressure.
The inner core is solid due to the immense pressure from the surrounding layers of the Earth. The pressure is so intense that it keeps the iron and nickel in the inner core in a solid state despite the high temperatures.
The inner core of the Earth is solid because of the immense pressure it experiences due to the overlying layers. Despite the high temperatures, the pressure prevents the inner core from melting. The high pressure keeps the iron and nickel in the inner core in a solid state.
The question's wrong there...the inner core is made out of SOLID iron and nickel. But if you were talking about the OUTER core, it is extremely runny and gooey iron and nickel and a piece of molten crust.
The rock found in Earth's inner core is primarily composed of iron and nickel. This molten rock is in a state of extreme pressure and temperature, creating a solid inner core due to the immense pressure.
