How many layers is the mantle divided into
WebThey're in our atmosphere. And the core, once again, its composition is fundamentally different than the mantle and the crust. We believe that it's mainly metals, and in particular iron and nickel. So that's the structure of the layers of the earth from a composition point of view, from a chemical point of view. WebEarth’s interior is broadly divided by composition and depth into crust, mantle, and core (Figure 9.2). The crust is primarily (~95%) made up of igneous rock and metamorphic rock with an overall composition between intermediate and felsic. The remaining 5% is made up of sedimentary rock, which is dominated by mudstone.
