To: meteorite-list@meteoritecentral.com Date: Tuesday, December 29, 2009, 9:02 PM OK, A friend and I were watching a show on Discovery or NatGeo a couple months back. The program I think was about asteroids, and impacts, perhaps even How the Earth Was Made or another program. Don't really remember The point is during the show they said very matter-of-factly on three separate occasions that the Earth's core was made of three different materials. One scientist (or narrator I don't remember) said Earth had a rocky core. Which we laughed at of course because we all know that the Earth's core is Solid iron right? Then another scientist confirmed our knowledge and stated what we already knew. The Earth core is made of SOLID iron. Of course we said! Now that's right... Then not 10 minutes more into the show another person stated that the Earth had a molten iron core. To make matters even more confusing the show went on to say that the SOLID iron core was surrounded by molten iron with lighter rocky materials floating out beyond that OK... sounded good at the time, but My question is simple. Which is it? Molten? Solid Iron? or Solid iron surrounded by molten iron. And if it's the latter how is this possible? Wouldn't the solid iron core NOT be solid if it were sitting in the middle of a molten lake of iron? Does the core cool faster than the surrounding material, and if so how is this possible considering this the logic that says an object cools from the outside in. Now, I'd like to stop there but I just read an interesting article on National Geographic's website titled North Magnetic Pole Moving East Due to Core Flux here: http://news.nationalgeographic.com/news/2009/12/091224-north-pole-magnetic-russia-earth-core.html At the end of the article it flatly states: ...Wandering Pole - Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid metal. This creates a dynamo that drives our magnetic field. Scientists had long suspected that, since the molten core is constantly moving, changes in its magnetism might be affecting the surface location of magnetic north I don't know about you, but this confuses me just a little bit... Can anyone please clear this up for me?
