Question

How deep is the Earth's core?

Answer 1

Hint: Our blue planet Earth consists of three parts: crust , mantle and core, here in the question we are being asked about the depth of the core from the surface of the earth.
Generally, it is considered that the core is about 6000km down.

Complete answer:
Earth's core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220km, which is about 20% of earth's radius or 70% of moon's radius. There are no samples of Earth's core available for direct measurement, as there are for mantle. Earth's core is considered to consist of iron and nickel alloy with some other elements. Surface temperature of Earth's core is estimated to be approximately 5,700K or 54300C.

The central point of the Earth is over 6000km and the outer part of the core is about 3000km below our feet. Even the mass of the Earth is located at the centre which is the core of the Earth. Most of the core is made up of iron filled in it, exact figures are yet to be found out. The outer core is in molten form and the inner core is solid due to the increased pressure at the centre.

Note: Till now, the deepest hole which was made to the Earth's core was created at the Kola Super deep Borehole in Russia which was only 12.3km deep. Other studies regarding the core of the Earth were made using a combination of particle accelerators, X-rays, high intensity lasers, diamonds and iron atoms.
