- dangayle 12y agoWhat about the water in the earth's core? >>A reservoir of water three times the volume of all the oceans has been discovered deep beneath the Earth's surface. The finding could help explain where Earth's seas came from. http://www.newscientist.com/article/dn25723-massive-ocean-discovered-towards-earths-core.html#.VIjQPWbvgSo http://www.newscientist.com/article/dn25723-massive-ocean-di...
- Balgair 12y agoMy wife looks at carbon in the deep earth, but water is a very related chemical in these cases. She says that the amount of water in the core is indeterminable at this time, but it is likely a lot more than a mere 3x the ocean volume (also, volume depends on pressure and temp, which are extreme in the core) Note: at extreme temps and pressures in the core, water as we know it is not a good guidepost. It may be crystallized or associating strongly with other exotic crystals and 'plastic'-y compounds at the Moho layer and other transition zones deep down. Also, just counting O and H elements is likely to not get you far there either. The story of how we got our oceans is FAR from complete. I'd wager we are in the 2nd page of the prologue though, which, for 60 years of real work, is pretty good compared to most fields.
