What material makes up Earth’s inner core?

Answer:

It can be said that the primary constituent of the inner core of the Earth is the solid iron combined with nickel.

This composition has not been done directly but requires information from other sources like Seismic Waves & models of the formation of the earth. The inner part of the Earth, which is its inner core, is surrounded by heavy pressure and heat; the temperature reaches up to the level that of the Sun, about 5,400 degrees Celsius or 9,800 degrees Fahrenheit and pressure is over 3 million atmospheres. However, due to the pressure at the centre of the Earth, these conditions maintain the inner core in a solid form. Nickel is found in the iron-nickel alloy, and based on the formation of the earth from solar nebula, the combination of these two elements might have stuck together. This solid inner core possesses a humongous significance in producing Earth’s magnetic field through the geodynamic effect it has with the surrounding liquefied outer core. Exploration of the inner core helps to shed light on the constitution, formation and geophysics of the earth’s interior.
