A Sial
B Sima
C Mantle
D Core

Correct Answer: Core

Core forms the major part of the total volume of earth. The innermost layer, forming the metallic centre of the Earth. Core of the Earth is like a dense magnetic ball of minerals (Iron & Nickel). Hence, it is also called NIFE (NI – Nickel & Fe – Ferrous Magnesium i.e Iron). Temperature increases at the rate of 1° Celsius for every 32 meters of depth.
