    this sounds like 'expanding earth' theory. what is your source for this staement ?

    and what is an 'underground' volcano ?
    lol, sorry, 'Undersea' not underground. The source, I cannot retrieve because I didn't bookmark.

    As is post #100, water molecules do not change size with temperature significantly enough to affect climate change.

    I didn't say the molecule size affected climate change but could it have an effect on rising water levels or even current shift?

    I was out of order with the comment. Apologies from myself, to you.

    OK, in that case it is irrelevant as the change in molecular size is many orders of magnitude smaller than the change in distance between the molecules resulting from the effect of temperature on density (which is due to the effect of faster translational motion inhibiting hydrogen bond formation and nothing to do with molecular size).

    Did your parents drop you on your head when you were born?
    cut the BS and give a citation for your statements. 'i did not bookmark them' is just an excuse. or did you make up that 'expanding earth' stuff yourself ?

    I do not know what Hannah's precise thinking is on this point, but superficially she is absolutely correct.

    The continental masses are a product of the evolution of the Earth through tectonics and geochemistry. Initially it is likely that the Earth was covered almost entirely by water. (Once temperatures had dropped sufficiently to permit liquid water.) As fractionation of magma sources produced silica rich and therefore buoyant materials these would form the early continents and produce the first land surfaces. I'm not clear why you doubt this.

    It would be nice to see a response from you, Chucknorium. My impression is that you jumped on what she was saying because she was developing a reputation for talking nonsense, rather than for talking nonsense. I may be doing you a disservice by suggesting that and it is only fair you have a chance to respond.

Unlike Mars for example, our gravity is high enough that we don't loose much H2 from upper atmospheric photo dissociation. Also we continue to receive some water from meteor comet ice.
    but we are loosing H2. also you said "most of the water"...what does it mean? that some water was on early earth or...

    Concerning the former sentence, the loss of H2 is tiny:
    Quote Originally Posted by Scientific American

    Concerning the latter, it is likely that he meant that the majority of the water on Earth was already present during the earliest periods on the geologic calender.
    I gave more information about that in another thread (cf. post #4).

    cogito ergo sum,
    lets say that abiotic origin of oil is right, when we make petroleum out of methane, hydrogen is leftout. hydrogen took oxygen from surrounded minerals and produce water. water dissolve silicate and sodium (salt perhaps being made). salt is lighter so it can rise trough magma. pressure force water upward. just if we look on earth as giant oven. we have all ingredients inside early earth. correct me if im wrong.

    I cannot follow your train of thought, to be honest.

    That would be entirely dependent on the debunked postulate of abiotic oil formation.
