Iron, though it does have a small amount of nickel.
The heat in the inner core is the result of several different sources. Some of these are: residual heat from the creation of the planet; heat caused by nuclear decay; friction; magnetic and tidal effects.
The inner core is located below the outer core with a reasonably higher temperature. The outer core also contains elements such as liquid iron and nickel while the inner core has others. Sorry if I am not being giving a huge amount of details.
no it has four main layers. They are the crust, mantle, inner core and outer core
The four main layers of the Earth are the crust, the mantle, the outer core and the inner core. The temperature in the mantle is estimated to be about 1000 degrees Celsius. Temperature in the inner core can reach up to 3700 degrees Celsius.

Oxygen is the largest component of crustal rock.
