Question

Q. Why does the core of the earth consists of iron instead of elements like hydrogen and
aluminium?

​

Answer 1

Answer

The core of the Earth is the innermost layer of the Earth. It is mainly composed of heavy metals like iron and nickel.

Explanation:

The Earth is divided into three layers: the uppermost layer, called the crust, the intermediate layer called the mantle, and the innermost layer, known as the core.

Hydrogen exists mainly as dihydrogen or hydrogen gas. Being lighter than air, it is not found on the earth's surface.

Aluminum is also a lighter metal. It is for this reason that it is mainly found in the uppermost layer, i.e., the crust, which is also called SiAl-a short form for Silica and Aluminium.

The core consists of the heaviest and densest material. It is for that reason that we see it is mainly composed of heavy metals like iron and nickel. The density of the core is around 13.6 gm/cm3.
