how did water come to earth hypothesis
Because their hypothesis requires that Earth arose from water-containing materials already present in the inner solar system, it's called the wet-accretion hypothesis. Most of Earth's water has an indigenous origin, says Drake.
Life is the process that resolves these disequilibria.. The water world theory suggests that the warm, alkaline hydrothermal vents maintained an unbalanced state with respect to the surrounding ancient, acidic ocean - one that could have created two chemical imbalances. The first was a proton gradient, where hydrogen ions were concentrated more on the outside of the vent's chimneys.
