Dissipation of cosmic gases from the Earths atmosphere

2 Dissipation of cosmic gases from the Earth s atmosphere 

The protoplanet forming the Earth was probably a disperse system containing materials in three phases (Szadeczky-Kardoss, 1968). Particles with greater density and dimension were found in the central part of the system. At a greater radial 

1 According to Rasool and De Bergh (1970) if the Earth were only 6% nearer to the Sun, the atmosphere of our planet would be very similar to that of Venus. 

It seems evident that the degree of dissipation was small in the case of the outer giant planets. This explains the fact that the atmosphere of these planets is composed of the above mentioned substances. Thus, according to Opik (see Cadle, 1966), 

Cosmic and terrestrial abundance of elements and their stable compounds under different conditions of temperature and pressure (Urey, 1952). The values of the dissipation losses are
