WebThe asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense as the rocks in the lithosphere. This allows the tectonic plates in the lithosphere to move around on the Earth's surface. WebAsthenosphere definition: A zone of the earth's mantle that lies beneath the lithosphere and consists of several hundred kilometers of deformable rock.

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. Below this temperature (closer to the surface) the mantle …

WebThe mesosphere works basically the same way. It provide a solid barrier so that the iron cannot go up, so the iron is basically confined to the layer of the earth it inhabits. Yes, the fluid in the core is extremely densely packed. The sheer pressure there compresses the iron atoms extremely close together.
