Questions for those knowledgeable in the fields of either Geology, Magnetic fields and Astrophysics.

To add to the geology question...

Did Japan move 8 feet towards the US? Or did 8 feet of the pacific plate subduct under Japan & the NA plate/fillipino plate?

And would that just make 8 feet less of ocean? or would that have already have been filled through sea floor spreading? Is there a giant gaping crack somewhere underwater?

An interesting point was brought up in this thread about water expanding when solidified, and I'm afraid it was brought up to prove something rather disingenuously. Water is one of the few substances that expands when cooled, which brings up another interesting trivia question, what else expands as it solidifies? A few metal alloys do and they are or were used in making hot type, the old letterpress type made from metal. Bismuth and antimony also expand when they freeze, as do some alloys that contain those metals. This is why bismuth and antimony are used in type-metal, which can be molded with great accuracy: The metal does not shrink as it solidifies, so it does not pull away from the corners and edges of the mold.

So an expanding earth goes against all theories of the earth's existence from a hotter more volcanically active molten state of most of the magna consisting of metal alloys that expand in a liquid state. Taken to an extreme, in time as the earth cools it would most logically contract in size, though this may not take place before the sun expands to it's red giant phase that could grow to the size of the earth's orbit. I'm no expert but I never looked into which will occur first. I do know that the earth's rotation is slowing and has throughout it's history, in the days of the dinosaurs a day was as short as 22 hours, nearly 400 days a year.

So if a cooling earth is taking place it should be shrinking. Haven't you ever wondered why there are only gas giant planets and not solid rock giant planets? Or is that just our local solar system coincidence?

Well i did not say we know how it fully works and sustains itself, but i said we know enough to at least know that it doesn't work the way you described it in the previous post.

because if the core was as sensitive as you mentioned, would be very dextrimental to us.

and we would never be having this conversation, as this planet would not be stable enough top generate life at all.

I didn't say that the core was sensitive, I proposed that it might possibly be getting smaller.

We know that the Earth's core is getting hotter, but why? Could it be that the fusion going on inside it, is working like that of a star? That when the matter being heated up becomes smaller (due to either being burned up or displaced), the heat that is generated becomes more intense?

So I conjecture, if the magma being injected into the outer layers of the Earth means that the core of the Earth is becoming smaller due to the the magma not being replaced, does this then account for why the core is getting hotter?

Is this what happened to Mars? It lost alot of it's core due to expansion of the surface, thus making the core hotter, thus making the magma more volatile, thus losing even more "fuel" in the core resulting in eventual volcanic death of the planet?

I certainly don't have the answers, but I don't throw out any possibilites until all avenues are explored. Please provide the evidence that "we know enough to at least know that it doesn't work the way you described it" please.

You will have to provide a link that explains the earth getting hotter, by all observations the earth has been cooling since it was formed.

Ancient Earth.

Well it depends on what the state of the said material is in, does it not? Liquid Iron has less area than that of the same mass that is in between states of liquid/solid Iron. like wise, liquid/solid Iron has a greater area of mass than that of pure solid Iron, but pure solid Iron has more area of mass than that of pure liquid iron. So therfore a transition of states would make expanding very possible, would it not?

So I conjecture, if the magma being injected into the outer layers of the Earth means that the core of the Earth is becoming smaller due to the the magma not being replaced, does this then account for why the core is getting hotter?

Covered already in my first post, when land that moves under another plate it is consumed by the molten magma, and the cycle continues to consume and eject.

Most earthly substances contract when cooled, and expand when heated, if contained, it's mass is the same but that mass in a gaseous state takes up more space.

Remember that science experiment in Jr. High? In a contained flask a match is ignited and burns up and gets smaller but the weight of the contained mass did not move the scale, all of the mass was present in different states.

I'm no expert here, but additionally, doesn't the magma come from the layer(s) surrounding the core and not the core itself?

I didn't say the Earth was getting hotter, I said the core. But you are right, it does appear to be cooling, but again could that be due to displacement of the "fuel"? I don't have the answers, just the questions! But I do have to question the answers to garner a better understanding, hope you don't mind!

I know what you said in your first post, but what are the chances of the exact same ammount of the tectonic plate being reconsumed into the layers of the earth to offset the expanding of the ocean floor? Surely it is not as black and white as that?


Likewise, the area of mass of solid Iron is greater than the area of mass of liquid Iron. So you have to look at the full cycle when looking at liquid magma, then just the cooling and shrinking of it when it is already passed the stage of pure liquid when it's reached the Earths surface.

Yes the core is solid and liquid magma surrounds it, it is the basis of the earth's electromagnetic field.

Convection of molten iron within the outer liquid core, along with a Coriolis effect caused by the overall planetary rotation, tends to organize these "electric currents" in rolls aligned along the north-south polar axis. When conducting fluid flows across an existing magnetic field, electric currents are induced, which in turn creates another magnetic field. When this magnetic field reinforces the original magnetic field, a dynamo is created that sustains itself. This is called the Dynamo Theory and it explains how the Earth's magnetic field is sustained. (From Wiki).

AmatuerSkyWatcher, I am no Geologist, nor even a scientist, I am just an amateur here. But here is what I see. Mother Earth is going through birth pangs, and the lands are beginning to shift. All that man/womankind has built will be covered and destroyed again. This has happened before, it is written in our history, and in the Monoliths all over the world. The Ancients marked the time, and told us what to look for, and when, but we have failed to heed the warnings. We cannot blast giant holes underground, and we cannot pump millions of gallons of oil from the Earth, nor dig billions of tons of coal, without suffering the consequences. Mother Earth is a living being, and she will react.

Things will get much worse before they get better.

It doesn't have to be precise, the earth is big and I don't intend to come off as condescending whatsoever. Indeed the earth's wonders are a balance of many fortunate things, with little localized releases of tension for ever until something really gives. But don't confuse the hot earth's magma to what goes on in stars, the earth doesn't have the mass to initiate nuclear fusion, and neither does Jupiter, that's why Jupiter will never be a star.

Thanks, but I was looking for scientific explanations/possibilties, sorry.

reply to post by Illustronic


Yeah i know, but it is thought that the Earths Core is like a giant fusion reactor right? And isn't a star just a massive fusion reactor? So there are some similarties, just those elements being fused are different, thus a different effect altogether?


I don't think you are being condecending, I just hope your patience can outlast my conjectures and musings!

Just thought that anyone new to the topic might like a link [url=http://www.halfpasthuman.com/aintwhatitusedtobe.html]

yes, jupiter can never be a star by itself. but it can be ignited by the right comet possesing the right elements to fire up that giant mass of hydrogen.

s**t happens

Sorry didn't see this reply. So therefore, if it is not precise, it is therefore possible that more molten magma can be forced up then goes down, thus causing an expansion of the Earths diameter in either of the X,Y or Z axis of it's dimension right?

The difference is a star can create iron but our earth cannot, it got it's iron core from the nebula of a past exploded star that gave genesis to our star and solar system forming. There is also limitations on the size of stars to create heavy elements from hydrogen like helium, oxygen, on up to iron and nickel. without stars there'd just be a bunch of unorganized hydrogen and subatomic particles floating about aimlessly. Some refer to that state of matter as the Big Chill, their believed ultimate destiny of the Universe, spreading out to absolute zero.

I myself think some theorists underestimate the force of gravity. Just my pedestrian opinion.

So do you think, however unlikely, that the Earth's surface could expand theoretically?
