Talk:Geophysics

message: I see that someone has been adding to this section and would like to share my thoughts on how I'd like this page to develop. I added the sections Physical Phenomena and Regions of the Earth with the following goals in mind:
# In Physical Phenomena, emphasize the physics to show what makes it geophysics.
# In Regions of the Earth, describe applications to the solid Earth, hydrosphere, cryosphere, etc. (still a lot to do here!)
# Pack in as many links to relevant pages as possible.
I reorganized the old material, putting most of it in The magnetosphere, Other fields and related disciplines and Methods of geophysics. I have been tempted to phase out Other fields and related disciplines as the material gets covered in other sections. But perhaps it might be useful to keep it as a description of how geophysics is organized in societies like AGU and IUGG. I'd be interested to hear what other editors think of my overall plan.

thread_title:  Other fields and related disciplines 

message: Certainly, the regions of the Earth are important (in an abstract sense), but would the section on "Regions of the Earth" more properly be in the Wikipedia article on the "Earth" itself? I ask because this article on "Geophysics" could rapidly become very big if we try to fill out the "regions of the Earth". We might choose to simply constrain this particular article on "Geophysics" to what geophysics is about, which are presently listed in the section of "Physical Phenomena". What do people think?

replies: text: The point is to show the how instead of the what. For example, Structure of the Earth Interior is more about seismology and gravity than about the interior itself. The section could also be called "Applications", I suppose. RockMagnetist (talk) 19:08, 9 August 2014 (UTC)
replies: text: "Domains" studied by geophysicists. I suspect you like that word. DoctorTerrella (talk) 19:41, 9 August 2014 (UTC)
replies: text: Actually, I'm not familiar with its use in geophysics. RockMagnetist (talk) 19:46, 9 August 2014 (UTC)
replies: text: Magnetic domain, as in rock magnetism. I'm agreeing with the sentiment of your comments. DoctorTerrella (talk) 19:52, 9 August 2014 (UTC)
replies: text: Oh, right. That was obtuse of me! RockMagnetist (talk) 20:24, 9 August 2014 (UTC)

text: By the way, I agree with your concern about the potential for this article to get too big. I think the connection to the applications is needed, so the treatment will have to be very concise. Where a main article for a subject exists, Summary style can be used. RockMagnetist (talk) 20:33, 9 August 2014 (UTC)

text: To supplement what I said above - I particularly like the example of the Earth's interior because it pulls in so many different areas - gravity, seismology, mineral physics, thermal physics, fluid mechanics, and so on. RockMagnetist (talk) 19:48, 9 August 2014 (UTC)
replies: text: The problem is this: The Wikipedia page Earth is already very nice. (For some reason, not open to editing, but that may be a different issue.) Given that that page already summarizes the Earth's interior, tectonic surface, hydrosphere, atmosphere, etc. I wonder whether (not a pun) we need to try to reproduce it on this page. We might just summarize it, possibly with one paragraph? I'm sure that the Wikipedia culture would frown upon simply copying those sections in Earth to this article on Geophysics.

replies: text: About Earth: It is a featured article, which means it is recognized as one of Wikipedia's best. It is semi-protected, probably because it is frequently vandalized. You need to be autoconfirmed to edit it; at the time you wrote the above message, your account hadn't existed the requisite 4 days. Now you should be able to edit it.

replies: text: Thank you. DoctorTerrella (talk) 23:37, 11 August 2014 (UTC)

text: About "reproducing" Earth: To repeat what I said above, the sections in Regions of the Earth are about the how, not the what. If you compare them, you'll see there is little overlap between Structure of the interior and the Internal structure section of Earth, or even Structure of the Earth. I think such a section is important because it shows how the different kinds of physics are combined to determine what we know. RockMagnetist (talk) 23:39, 11 August 2014 (UTC)
replies: text: Okay, I will consider your point more carefully. My apologies. 23:44, 11 August 2014 (UTC)

message: I don't recommend putting in placeholders for sections unless they will soon be filled. Otherwise, it won't be long before a drive-by tagger will put an  tag in each section. Better to edit the to do list at the top of this page. RockMagnetist (talk) 19:05, 9 August 2014 (UTC)
replies: text: Okay, I understand. ;-) DoctorTerrella (talk) 19:08, 9 August 2014 (UTC)

message: heat flow, should also include , also describe,
how IR (infra red), although quickly absorbed, sequentially transfers heat upward, via higher-to-lower temperature 'osmosis' , soto speak (sorry, i did biology first) ... when higher temperature materials deeper down, generate more IR from pressure, but are not heated FROM other IR as easily, whereas when the cooler stuff higher up, can be heated up more easily, rather than IR being LESS likely to cause FURTHER heat increase (more agitated are more affected by collision forces ... rather than cooler/near zero temperature material being atomically, still, and YET, to become when then hot, less easily agitated FURTHER, from IR, whereas collisive forces (further pressure, rapid mixing (not the case in magma/mantle) , etc , does - a lab-mixing-tube-spinner) do...
... so,.. as, IR is sequentially more penetrating of also LESS DENSE earth above it, IR does get through, not the whole crust!!... but through however-thick an amount,
but since that continues to happen sequentially-UPWARD...
and CONSTANTLY,
it never stops,
IR can be said to ALSO, be a part of the heat flow, "a contributor" if i remember correctly,
to the lower minimums, rather than hot-spot maximums, etc

message: The article has left out the rotation of the earth, and all its complexities, as a subject of geophysics. Bdushaw (talk) 01:54, 19 February 2019 (UTC)
replies: text: Yes, rotation should definitel be in there. Thank you for pointing that out. RockMagnetist(talk) 16:13, 21 February 2019 (UTC)

message: The discussion of water seems out of place in the mineral physics section. Certainly water can be an important aspect in mineral physics, but the present discussion if very off topic.
