The most abundant element in both the Earth's inner core and outer core is iron. It makes up about 85% of the Earth's core composition.
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.
The core of the Earth is thought to be mainly composed of iron and nickel, with a solid inner core and a liquid outer core. The inner core is under immense pressure and temperature, causing the iron to solidify despite high temperatures. This composition is based on seismic waves and studies of Earth's magnetic field.
the inner core,with a radius of 1400 km is belief to consist of Nife(dense Nickel Iron alloy) which is forced into solid state by increased pressure.
