Answers
Answer:
Explanation:
There are three compositions of the earth's interior.
Crust :-
It is the outermost covering of the and 8-40 km thick.
It is 1% of the earth's volume and about 0.5% of the earth's mass and brittle.
It is between the hydrosphere and crust and is termed as the Conrad Discontinuity.
Mantle :-
It is the portion of the interior beyond the crust called the mantle.
It is about 2900 km in thick and 84% of the earth’s volume and 67% of the earth’s mass.
it is between the crust and mantle is called and called Moho discontinuity.
Core :-
It is the innermost layer of the earth’s surrounding center.
It is about 15% of earth’s volume and 32.5% of earth’s mass.
It is between the upper core and the lower core and is called as Lehmann Discontinuity.

Crust :-

we get minerals like silica , aluminium and magnesium.
Mantle :-
It is the portion of the interior beyond the crust called the mantle.
It is about 2900 km in thick and 84% of the earth’s volume and 67% of the earth’s mass.
it is the thickest layer compared to all layers
Core :-
It is the innermost layer of the earth’s surrounding center.
It is about 15% of earth’s volume and 32.5% of earth’s mass.
we get iron and nikel from this layer .
it also called nife.
