WebFrom 4.5 to about 3.8 bya, the Earth was in a period of heavy bombardment. Earth’s surface was being pummeled by comets and meteors, sterilizing the impact zones. The much closer Moon would have created enormous tides that would have washed any emerging concentration of monomers in a warm little pool out to sea. http://www.chm.bris.ac.uk/motm/oec/motm.htm

WebThese vents are the only places on Earth where the ultimate source of energy for life is not sunlight but the inorganic Earth itself. Did life begin at deep-sea vents? This is one theory, and it is supported by several lines of evidence. First, some of the thermophilic, or heat-loving, vent microbes are the most primitive organisms known on Earth. WebView of the first high-temperature vent (380 °C) ever seen by scientists during a dive of the deep-sea submersible Alvin on the East Pacific Rise (latitude 21° north) in 1979. Such geothermal vents--called smokers because they resemble chimneys--spew dark, mineral-rich, fluids heated by contact with the newly formed, still-hot oceanic crust ... Web20 Aug 2024 · Shallow-water hydrothermal vents (<200 m in depth) have a widespread biogeographical distribution, generally associated with active submarine volcanism, and can be considered as intermediate environments between deep-sea and terrestrial hydrothermal systems ( Tarasov et al., 2005 ). dcs change vr hangar
