Your answer was interesting, but I'm indeed looking for a thermal answer rather than a (geo)chemical answer.
Do you think Earth can be considered as some kind of solid gaz, or at least as complex system, in order to study it trough a thermal/energetical point of view? Is it what you call an...
This is an interesting element of answer. But why does the materia doesn't accumulate anymore (isn't solid anymore) beyond that greatest gravitational potential field (6400km)?
Calculate Earth's radius with the help of some chosen parameters (something like internal energy, temperature and...
Yes indeed the evolution of Earth internal energy determines the evolution of its diameter.
But my question is rather how does Earth internal energy determines its diameter (statically talking)?
borek (numerology salad blabla), i apologize for my lack of vocabulary but I beg you to try to...
well let's admit the mass, but the density has to be explained !
does Earth internal inergy alone can parametrize Earth density?
In such a case, how do we determine Earth internal energy? Earth initial internal energy + energy lost in the external system (cooling within the universe) + energy...
Well, the french (again) wikipedia has two different articles : one for "phase transition" (transition de phase) which I quoted, and one for "state transition" (changement d'état) which seems to be a subcategory of phase transition. But let stick to you definition (you have 20345/7= 2907 times...
As a phase transition is defined in math-phys as non-analyticity of certain parameterized functions on a configuration space IN the parameter variable, we can consider the non analicity of internal energy (or pressure if you prefer) depending of the Earth radius parameter, at any point of the...
Yes of course.
Definition of the french wikipedia
id est
Since (darwin123) that we have a drastic change of the composition at the Earth surface, we can indeed consider it as an abscissa. But I guess that overall we should consider altitude 0 of our Earth system the same way we...
The phase transition is also obvious trough the temperature point of view
On the attachment I draw Earth temperature gradient (0 km = Earth center on the graphic ; 6400 km = Earth radius).
OK thank you, that means that we assume to be the center of our environnement . Why not (but it's a rather old school style)
I appreciate your answer Borek, but I'm sorry to say that according to wikipedia you are wrong.
That's why I ask for your help again : what is the mathematic...
Hello, I ask for your help because I can't find any information about Earth crust-atmosphere phase transition. I noticed indeed that our feet tread upon a solid surface, while our nostrils breath a gazeous compound !
This remark seems so obvious that I can't find any description neither...
