The immense pressure from the layers outside of the inner core.
Heat and pressure.
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 amount of pressure overcomes the material's disposition to melting at high temperature. It solidifies.
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.
Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
The immense pressure from the layers outside of the inner core.
they go in or out because of pressure from the earths core

Earth's core
Pressure from the earths 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 amount of pressure overcomes the material's disposition to melting at high temperature. It solidifies.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
no it is not true. there is solid iron and nickel in the Earths core
The Earth's core is about 1200km thick. it is mostly iron, and is solid due to extreme pressure. The temperature can be up to 7000 degrees.
The core is 33% of the Earths mass
