What is the name

[@vishuverma9988]

This question can be silly for everybody but I want to clear my doubt once, as we know it's almost impossible to reach the center of the earth, then how we got to know that core is made up of nickel and iron? Are we assuming or we have evidence as well? If someone can answer ?

[@AAKASHGUPTA-iv7pd]

There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field.[3] The inner core is believed to be composed of an iron-nickel alloy with some other elements.

[@Villagerman-sigmu]

We know it's made of iron because the earth is a magnet. Very few elements are magnetic, and iron is the most common one. There's probably a little bit of nickel and cobalt in there too. In addition, molten elements will separate into layers by density, with the most dense one sinking to the bottom.

[@Villagerman-sigmu]

We know that the earth core is in liquid form and due to the heat and pressure the molten magma comes out from the earts core and this is the way we know there is iron and any other mineral
