Thank you~

Answer 1

I guess the answer is A and C

Answer 2

Answer:

Option- (A) and (C): Both, of them are valid points.

Explanation:

• Materials differentiation inside earth's layers:

Earth layers are differentiated in the different layers of earth layers, on the basis of different properties they have, as the earth is made up of a very fine layers of different elements.

Below the continental plates we have, the following layers inside earth's structure:

1. The mantle,
2. The outer core,
3. The inner core.

• As due to earth's properties it cools down all the materials in such a manner that the denser material sinks to the center, while the less dense floats near to the mantle layer of the earth.
