Earth's Core Has Another Layer, Scientists Claim

The Earth's core is composed mainly of iron

Probably. But I'd like to know how it got there, from the swirling clouds of hydrogen that sort of clumped together to form the proto-planets I mean.

From the millions of degrees of heat down there, heat turns hydrogen into iron, just ask Al “baby doc” Gore, it’s just releasing it’s inner Chakra........

Where does all the heat come from?

From the exploded Super Nova that created our part of this end of the galaxy.

They always have a supply of the heavier elements.

That stuff comes in the form of tiny dust particles in and amongst the gas clouds.

Eventually gravity pulls it back together; it all heats up; the dust particles melt from the heat of gravitational compaction; and suddenly it all settles out with most of the heaviest stuff at the bottom (uranium, gold, iron), and the lighter stuff at the top (silicon, carbon, nitrogen).

From that point on it just takes a bit of time to resettle more of these materials until you get a hard surface crust.

We get the rest of our iron and other heavy metals through collisions with smaller bodies ~ small planets, meteors, moons, space junk, and so on.

it all heats up

Sure it does!

You don't really beleive this stuff, do you?

So, the "footnote" ~ does that appear anywhere but at the Nature site?

The accessibility of those bands may well ultimately affect the value of gold and totally debase the stuff.

[muawiyah]

Of course. Didn't God "look up on the face of the deep" and then He said "Let there be light" ~ that is, electromagnetic radiation of all frequencies ~ and we know if you produce such radiation you can heat stuff up pretty good ~ whether it's at a campfire, a home stove, a giant iron ore smelter, a thermonuclear bomb......

There are so many ways we can take simple "light" to torch stuff I can't begin to list them all.

Now, do you dispute the Bible? Do you doubt that God can make galaxies, suns, planets, layers of post collision melt in the bowels of the Earth?

[NonValueAdded]

Yes, it does. Fire ants. A very thick layer too.

Aluminum, Super-sonic, Nazi-hell creatures from the center of the hollow Earth are gonna eat us all...

Ok, maybe not. I just thought I’d throw that out there. ;-)

[Dead Corpse]

Now we know where nougat REALLY comes from.

The planets weren't formed from 'swirling clouds of hydrogen'. If you are serious you can google and find some nice resources on star and planet formation. Really quite interesting.

[agere_contra]

True.

We are literally made from the dust of stars.

It's the best explanation so far.

I don't pretend to know, unlike most people.

Yeah. Sort of like wondering what keeps airplanes up in the air. One possibility is that the tooth fairy does it; and the other is that planes harness the gravitation forces of extraterestial bodies. One of those is best too.

Actually it is because airplane wings deflect particles of the air in a downward motion. For every action there is an equal and opposite reaction.
