Editing Earth's outer core (section)

==== Consequences for Earth's accretion ====
Models of Earth's accretion could be better tested if we had better constraints on light element [[concentration]]s in Earth's outer core.<ref name=":0" /><ref name=":9" /> For example, accretionary models based on core-mantle element partitioning tend to support proto-Earths constructed from reduced, condensed, and volatile-free material,<ref name=":0" /><ref name=":8" /><ref name=":9" /> despite the possibility that [[redox|oxidized]] material from the outer [[Solar System]] was accreted towards the conclusion of [[accretion (astrophysics)|Earth's accretion]].<ref name=":0" /><ref name=":8" /> If we could better constrain the concentrations of [[hydrogen]], [[oxygen]], and [[silicon]] in Earth's outer core, models of Earth's accretion that match these concentrations would presumably better constrain Earth’s formation.<ref name=":0" />
