Naturally it is not 100% homogenized,but we find lots of iron embedded
in surface rock in every part of the world.Most of iron is at the earth's center. Why is any at the earth's surface?. Same has to be true of uranium. Lots of aluminum near the earth's surface. Can't see that element near the earth's core,but who knows? If there was aluminum near the core I could create a nice theory on magnetizum. Seem when the earth was a very hot liquid all the elements should have been in layers heavy elements making up the core going up to gases to the surface(yes)? Well things can be tricky Put small light marbles mixed in with large heavy marbles in a large jar,and shake the jar very well and you will find the heavy large marbles on the top (go figure) Bert |

As for the final placement of matter, I think that can be easily answered by the constant churning that the earth does. Earth Quakes, Volcanos, Plate Tetonics. The earth is getting shaken and stirred, so maybe those heavy layers are down deep, but they keep getting pushed to the top with the rest of the ice and gin...I mean rock and stuff. BV. |

It is all getting continuously jumbled up.
There is a constant slow turnover of surface material. Generally, new material wells up along areas called mid-ocean ridges and eventually gets buried again in other locations called subduction zones. Most of the surface which does this recycling is located on the ocean floors. There are other areas of more permanently floating crust that can move, break up and rejoin in response to ocean floor movements. These are the continental plates. Mid-ocean ridges and subduction zones are both subject to earthquakes as are areas where continental plates are being forced together. All of this surface movement is thought to be driven by convective forces in the interior. Sally "G=EMC^2 Glazier" wrote in message ...

All of this surface movement is thought to be driven by convective forces in the interior. In addition most of the iron outside the core is in the form of silicates, oxides, and so on, which have much lower densities than metallic iron or iron-nickel -- instead being comparable to the other materials in the mantle. So unless there's some sort of chemical process at work that causes metallic iron to 'precipitate' there's no reason to expect the iron to 'gravitate' towards the core. Compare with water, which of course is much less dense than any of the minerals in the earth's interior or crust -- yet only about 1% of the water in the planet has managed to find its way to the surface over the past 4.5 billion years or so. --Odysseus |

BTW...the only other body in the solar system known to currently have a
recycling surface is Io. Sally "Sally" wrote in message ... It is all getting continuously jumbled up. There is a constant slow turnover of surface material.

no you will find the large marbles on top regardless of the difference
in specific gravity between large and small. Wreaks havoc machines that produce "combination of ingredients" pharmaceuticals. The size difference can be quite small for the effect to take hold, G=EMC^2 Glazier wrote: Naturally it is not 100% homogenized,but we find lots of iron embedded in surface rock in every part of the world.Most of iron is at the earth's center.

I think you will find that the large objects can either settle to the
bottom or rise to the top, and it doesn't depend in any simple way on density. The "cereal-box effect"?? Something like that. There's a lot of research on it.

To add to the mystery we find gas pockets locked in the earth's surface.
We find no hydrogen,or helium in the atmosphere,and that is logical. Don't seem logical to find say a mile below the earths crust these two gases. Is there a theory on this? The two gases are mixed together,and the ratio is 1% helium. Helium does not bond to other atoms so it is very easy to separate. It is not rare today and is very cheap to buy. Has only a few uses.

An emailer asked why helium is so plentiful today? The reason is a smart
chemist 25 years ago working at Exxon city in Colorado found 1% helium mixed in with the hydrogen that comes out of oil wells. This is true all over the world. That was true in the days of the Hindenburg,but Germany did not have a smart chemist to check it out. There is a reason why hydrogen is not twice as buoyant as helium,but I forgot how it goes? Bert |

Helium is element #2 on the atomic table. He is what is called an inert
element because all the electron orbital positions are filled and no chemical combinations are possible. Hydrogen fills the #1 position and with only one proton it has only one electron in orbit. This leave one electron orbital position open for chemical combination. Hydrogen is very reactive due to this and forms a bond with the first available atom. For the most part this is another Hydrogen atom, not always but for this discussion that is what we are considering. Now Hydrogen has an atomic weight of 1.something per atom, Helium has an atomic weight of 2.something being slightly less than two Hydrogen weights, this difference is what is laughingly called a Hydrogen bomb. Now if the He atom occupies 1 unit of space due to the fact that it has two protons, two neutrons and two electrons, then the H2 molecule occupies slightly less space due to it's lack of the two neutrons. The actual difference in lift between 1H2 and 1He is about 94% in favor of 1He. Hydrogen lifting less than Helium. Germany with it's lack of natural petroleum reserves could not produce Helium in sufficient quanties for use in lighter than air craft. The US Navy could not even afford to have enough helium for two of it's rigid airships, they had to share. Germany tried to obtain quantities of helium from the US but was refused because the government was afraid of the possibility that it could be used for war purposes. 38 people died in New Jersey as a result and an industry was destroyed with the Hindenberg in 1938. Some minor points in my rather long winded dissertation may be in error but the general point of what I am trying to say are correct. Exact numbers are not presented because I don't feel energetic enough to look them up. G=EMC^2 Glazier wrote: An emailer asked why helium is so plentiful today?
