WebbMcCrea, W. H. A theoretical model of the formation of the solar system is proposed, the fundamental hypothesis being that a cloud of interstellar matter, compressed in a shock region of the Galaxy, condensed to form the solar system. The material in the cloud was in a state of supersonic turbulence, treated as though it were composed of floccules. Webb1 feb. 2000 · Features.

According to the giant impact hypothesis the Moon formed from a colossal impact of a hypothetical protoplanet called Theia with Earth, early in the Solar System's history. Webb4.12.4.1 Losses During Accretion. As growth of a protoplanet proceeds with increasing accretional energy, shock-induced devolatilization of the accreting materials occurs and volatile species are transferred into the growing atmosphere, limiting the amounts of volatiles that can be buried into a planet. shows downtown tucson az
