Question

Explain why scientists believe the Earth developed in a series of layers.

Answer 1

The earth has different layers for a reason similar to chocolate milk. When you put chocolate syrup in milk, where does it immediately go? To the bottom. We don't exactly know how the earth itself formed, but the way it developed its layers is by the heaviest elements sinking to the bottom. The earth's core is made of iron and nickel, with maybe a little sulfur - that's the heaviest part. The mantle is made of heavier minerals in the silicate family, and within the mantle there are certain regions where there is a "phase transition" from one type of crystal structure to another, where the weight of the overlying layers is heavy enough to squish the atoms closer together. The lightest material floats like a crust on top - we call it the crust of the earth, even.

Answer 2

The earth has been developed in a series of layers that lead to the formation of the core, mantel, and crust. Most scientists believe that the exitance of the layers is rocks and minerals present.

Why does the earth have layers ?

Due to the composition and structure of the planet earth being made of diverse elements they are arranged and grouped in a series of layers that are arranged over each other and form the series of pathways for the development of the above layers. Like that sedimentary rocks have layers the oldest at the bottom and youngest at top.
