What accounts for Earth's mass being an extreme concentration of the non-volatile component of the original cloud?
Answer
Light gases were stripped from the inner regions by photo-evaporation or migration
The inner Solar System experienced selective removal of light gases (H and He), leaving behind only the high-melting-point materials—metals and silicates—that constituted the mass of terrestrial planets like Earth.
