A canopy would also reflect and absorb considerable sunlight. How then could many tropical plants, which require much sunlight today, have survived under a preflood canopy?
The Nucleation Problem. To form raindrops, tiny particles, called “nuclei” or nucleation sites, must be present to initiate condensation. However, falling rain sweeps up these nuclei and cleanses the atmosphere. This reduces further condensation. Rain from a vapor canopy would actually choke off rain production for a time. Some have claimed that volcanic eruptions, beginning suddenly at the time of the flood, continuously ejected nuclei into the upper atmosphere. This does not explain why volcanic eruptions suddenly began globally, then quickly and continuously distributed nuclei throughout the atmosphere for several weeks. Volcanic eruptions, rather than contributing to the flood, require special conditions that seem to be a consequence of the flood. Both the nuclei problem and the heat problem show that condensation did not produce most of the flood’s rain. It seems more likely that ” geshem rain” was produced by the powerful jetting of the “fountains of the great deep” which caused
