The temperature at the inner core s surface is estimated to be approximately 5700 k 5430 c or 9806 f which is about the temperature at the surface of the sun.

The inner core is believed to be composed of an iron nickel alloy with some other elements. It is a solid metallic ball made mainly of iron. Unlike the core s outer layer it is mostly solid. It s solid because at that depth the high pressure overcomes the effect of high temperature.

The iron inside is hotter compared to the outer core as well as it is 10 000º f or 5537 778º c. It became clear that the core consists of a thick shell of liquid iron the outer core with a smaller solid inner core at its center. This new study concludes that it s most likel. 9 800 f which is roughly the same as that of the sun.

At the very centre of the earth is what is known as the inner core. Protected by the liquid outer core mantle and crust the inner core is a hot solid ball of highly pressurized nickel and iron with a temperature of approximately 5 700 k 5 430 c. The inner core is the fourth layer inside the earth. Unlike the outer core the inner core is mostly solid.

Earth s inner core is made mostly of iron and nickel but 5 percent of it has been a mystery for a long time. Ni for nickel and fe for ferrum also known as iron. The inner core which is about 750 miles thick is made primarily of iron. The inner core is a solid ball composed of an element named nife.

Although the inner core is very hot it is not liquid like the outer core. Here temperatures reach extraordinary levels estimated to be between 7 200 8 500ºf 4 000 4 700ºc.
