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. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere-asthenosphere boundary is conventionally taken at the 1,300 °C (2,370 °F) isotherm.
