The immense pressure from the layers outside of the inner core.
Heat and pressure.
it remains solid because of all the pressure. Also, it is solid because it is the inner core
The amount of pressure overcomes the material's disposition to melting at high temperature. It solidifies.
Earth's inner core is solid due to the exceptionally high pressure (approximately 330 to 360 GPa) which drives up the melting point of iron beyond the temperatures found within the inner core.
The immense pressure from the layers outside of the inner 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
they go in or out because of pressure from the earths core

The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
no it is not true. there is solid iron and nickel in the Earths core
