timescale of Earth's formation from the solar nebula? (Select all that apply.)
Since Earth is an inner planet, it was more likely to have been hit with planetesimals that were
scattered by the larger outer planets.
Water vapor and atmospheric materials could have come solely though bombardment if Earth
wasn't heated by radioactive decay.
Earth's atmosphere could have only formed through outgassing since there were no planetesimals
that contained water.
If the Earth differentiated rapidly, atmospheric material likely arrived via bombardment by
comets and planetesimals.
If the Earth differentiated slowly, atmospheric material was likely released by volcanic
outgassing.
