Influence of the greenhouse effect in primordial atmospheres on the formation of the earth and Venus

The greenhouse effect in the primordial atmospheres possibly formed by degassing of volatile materials in the interiors of the earth and Venus which mainly contained CO2 and H2O in the ratio of 1 to 4. It was shown that the earth atmosphere greenhouse effect could not have resulted in the heating of its surface to temperatures above those of boiling water; this contradicts the theory of the condensation of planets of the terrestrial group from a gaseous solar nebula, the theory of the rapid accretion of meteoric material, and the theory of capture of the moon by the earth. It is concluded that only slow accretion of the earth and formation of the moon in a near-earth orbit allow for the existence of a primordial atmosphere of the earth with low pressure which does not hinder the beginning of the hydrosphere.
