Question:– What is the thickness of the Earth’s inner core?

Answer

The Earth’s inner core is roughly the size of the country of Brazil, with a radius of about 1,220 kilometers (758 miles).

The inner core of our planet lies in the center of the Earth and forms the deepest layer in the planet’s composition. It is also made of iron and nickel and is dense and spherical with average temperatures of about 5,400 degrees Celsius or 9,800 degrees Fahrenheit. This deep pressure does not allow the inner core to melt even when temperatures get to those at the surface of the sun. First detected in 1936 by a seismologist Inge Lehmann, the information about inner core remains still expanding. New findings indicate that it might have multiple hierarchical levels and that it may even have a core. Thus, the inner core is directly involved in the process of the generation of the Earth magnetic field via its interaction with the outer core in form of a liquid. It is since its properties and behavior that help to explain the formation, evolution, and the current geodynamics of Earth.
