Is water conserved?
Is there any natural process which alters the quantity
of water on earth, net? if not, does that imply the amount of water is unchanged since planetary formation? -- Rich |

Water has been lost by space craft. Some diffuses out of the Earth's atmosphere. Nuclear fusion bombs and experiments use up hydrogen derived from water. Be more sophisticated in your question. -- Sam Conservatives are against Darwinism but for natural selection. Liberals are for Darwinism but totally against any selection. |

"RichD" wrote in message ... | Is there any natural process which alters the quantity | of water on earth, net? | Yes and no. Water vapour (a gas) will escape the Moon and lighter gases such as helium and hydrogen will escape the Earth. So if enough energy splits the water molecule when it is already high in the atmosphere the oxygen being heavier falls back and the hydrogen can escape. On the positive side the Earth can pass through the tail of a comet and collect water. Both of these processes are possible but uncommon and miniscule. | if not, does that imply the amount of water is | unchanged since planetary formation? | Yes. Sea levels can fall if ice is piled high on land such as Antarctica and Greenland and can rise if the ice melts, but the total quantity of H2O is constant. The archeological record shows man and mammoth once lived on land 12,000 years ago that today is the North Sea. Fishing trawlers regularly net mammoth bone and even weapons from the sea floor. |

Well, it certainly is, and the biochemical splitting of water by photosynthetic organisms is/has been responsible for oxygen in the atmosphere. Of course, living organisms also synthesize water, but the overall water balance on the earth has indeed been altered by the progress of life. |

Google. Assuming that you mean liquid water, then of course earth had only water from when its surface cooled below 100°C. In a good TV show the comment was: "and then it rained.... torrentially, all over, day and night for millions and million of years" It is also hotly debated whether the planet still gets "snowed" upon, from outer space, today, after the main amount of water was brought here during accretion and from comets and meteors. On the other end of the spectrum of this issue is the theory that ALL water will eventually be absorbed by hydrating of Alk. Earth Metal Silicates, rocks, and the world will become bone dry. Water then can be only extracted if the hydrated rock is heated to some 400°F. -- An analog sample is Gypsum: Mix Gypsum with water and it absorbs the water and gets hard. Heat that hard gypsum to some 250F and the water comes out and the Gypsum get powdery again: CaSO4+2H2O = CaSO4*2H2O Of course, all that is what "they" say. I wasn't there.... ...ahahaha..

For a long time the leading theory as to the origin of the water in the oceans was comets, but that no longer seems likely. Nevertheless, it still may have been a significant source. http://neo.jpl.nasa.gov/news/news008.html |

One of the early supporters of Hörbiger's theories was Houston Stewart Chamberlain, of English ancestry. He was the leading theorist behind the early development of the Nazi Party in Germany. In 1923 Hitler visited Chamberlain with several highly ranked members of the Nazi party.[26] Chamberlain's ideas were influential, in particular onto Alfred Rosenberg, who became the Nazi Party's philosopher.

Dear RichD:

Net gains: - temperature low enough to retain hydrogen and oxygen atoms (fail hydrogen, pass oxygen) - some braking mechanism for hydrogen / oxygen from solar wind (pass, magnetic field) - some atmosphere already present for braking (pass) Net losses: - single hydrogen atoms at the temperatures at the top of our atmosphere, have enough KE (if not necessarily the right direction) to escape Earth's gravity well. Net conversions: - clathrates and "polymers" - photosynthesis So no, what we have now is what we have now. The future hold probably both more and less water. David A. Smith |
