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.

http://www.differencebetween.net/science/differences-between-the-earths-lithosphere-and-asthenosphere/ WebThe asthenosphere, a less rigid region from 100 to 700 km beneath the surface, separates the lithosphere from the mesosphere. Where the asthenosphere sinks back down to deeper levels, it drags the overlying plate down with it, creating a convergent plate boundary called a subduction zone.
