Question

The earth's major layers formed because ________. the earth was heated after its formation resulting in melting and redistribution of major chemical compositions the chemical composition of the solar nebula changed over time the earth's mantle grew like a crystal forming around the earth's core but the crust was exposed to space and stayed more like the original material radioactive decay caused materials to change over time and resulted in the layering

Answer 1

the earth was heated after its formation resulting in melting and redistribution of major chemical composition

Step-by-step explanation:

• Earth has formed some 4.3 billion years ago with the formation of the universe and since then it is arranged in various layers and that has been due to the formation through the pressure and heat build-up inside the earth's surface.

• With the changes taking place in the chemical companion of the planet the earth formed in various layers and thus is a product of the same.
