The distribution of elements on Earth is determined by planetary differentiation and nucleosynthesis.
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
Geochemical and cosmological evidence strongly supports the view that the distribution of chemical elements on Earth and other rocky planets is fundamentally governed by nucleosynthesis (which provides the initial inventory of elements) and planetary differentiation processes such as core-mantle fractionation.
