Earth’s ‘solid’ inner core may contain both mushy and hard iron
WebOct 1, 2008 · Earth's layered internal structure has been established for some 70 years, on the basis of the reflection and refraction of seismic waves originating in earthquakes. But the innermost part of the Earth, the core, has been surmised to be solid, without clinching seismic evidence, until now. © Royal Astronomical Society 2008 Views 45,327 Altmetric WebDec 18, 2015 · $\begingroup$ I think Earth's outer core layer is still molten but the inner core is solid (due to pressure, etc). Also the solid part is growing as the molten part around it crystallises. So the question may benefit from editing to make it more clear. (Still a good question in my opinion.) $\endgroup$ – flake garage floor coating
