Question

Mention the layers of the interior of the Earth.

Answer 1

The structure of the earth’s interior is divided into three layers namely the crust, the mantle, the core.

1. Crust is the outer layer of the earth, where we live. The major elements of crust are silica (Si) and aluminium (Al). Hence it is named as SIAL.
2. Mantle is the intereior part beneath the crust. The major elements of the mantle are silica (Si) and magnesium (Mg). Hence it is called SIMA.
3. The core is the innermost and hottest layer of the earth. It is composed mainly of nickel (Ni) and iron (Fe). Hence it is called NIFE.
