Vedclass · Answer

(D) The Earth is divided into different zones based on the affinity of elements for different phases. $1$. $Lithophil$ elements are found in the silicate layer (crust). $2$. $Calcophil$ (or $Chalcophil$) elements are found in the sulphide layer. $3$. $Siderophil$ elements are iron-loving elements that are primarily found in the Earth's core,which is composed mainly of iron and nickel. Therefore,the region where main metals (like $Fe$,$Ni$) are concentrated is the $Siderophil$ zone. The correct option is $(d)$.

List-$I$ (Ores)	List-$II$ (Composition)
$a$. Haematite	$i$. $Fe_{3}O_{4}$
$b$. Magnetite	$ii$. $ZnCO_{3}$
$c$. Calamine	$iii$. $Fe_{2}O_{3}$
$d$. Kaolinite	$iv$. $[Al_{2}(OH)_{4}Si_{2}O_{5}]$

The region in which main metals are found in the Earth is called:
