The process of differentiation results in layering of the earth's layer, i.e. Formation of core, mantle and crust and certain elements gets enriched and depleted in the different layers of the earth. So the statement incorrect statement is plant forming atmosphere.
So the correct option is (A).
2. Differentiation was possible only because of the temperature of the earth was very hot.
So the correct option is (b) very hot.
3.Nebular hypothesis explains the origin of planets, moons, asteroids and comets.
So the correct option is (A). Nebular hypothesis.
