WebEarth consists of four major layers: the crust, mantle, outer core and inner core. While most of the layers are made of solid material, there are several pieces of evidence suggesting that the outer core is indeed liquid. Density, seismic-wave data and Earth’s magnetic field provide insight into not only the structure ... 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.
