Document Summary

Water in the solar system: ice core and liquid/ice clouds, earth (oceans) 400 billion billions gallons of water: (326 million/miles^3) Accretion of materials from formation of the solar system- continuous outgassing including water vapor (steam). Zircron crystals- high levels of an oxygen isotope that could only come from the reaction with water. Pillow lavas (3. 5 billion years ago)- underwater volcanism. Mantle rocks contain the components of water locked in rocks and minerals. Comets- ice, dust, rock (contain up to 50% water) Problem with comets: deuterium, ordinary water has no neutron but deuterium (heavier water), has a neutron. The rate of heavier water and regular water is 1:3200. Volume of water: 400 billion billion gallons 326 million mi^3. Earliest evidence of liquid water on earth= ~4. 3 bya. Western australia, 2001 zicron crystals, earth"s oldest terrestrial (cid:373)aterials. Oceans and pillow lavas basaltic extrusive rock (3. 5 bya)
