Talk:Propagating rift

[Untitled]
Nick. Can you help me find the deleted page so I can work on this? BrucePL (talk) 17:38, 21 March 2018 (UTC)
 * OK, Bruce. Because it was deleted as being a copyright vio, I'm unlikely to be able to get an admin simply to paste it back onto this page. If you can confirm you have email enabled, I'll ask the deleting admin to send the text to you directly for you to work on off-wiki. Is that ok? Regards, Nick Moyes (talk) 20:44, 21 March 2018 (UTC)


 * Yes, of course, offline. I get emails from WP. might as well email me FAMOUS also. Thanks! BrucePL (talk) 21:54, 21 March 2018 (UTC)
 * Request sent. Nick. BTW - Three thoughts:


 * 1) Do remember to ping me or include my username in replies if you're responding to me from one of your own userpages - that way I see pretty speedy online notifications of your responses, but not if you don't. Although I do put pages like this on my Watchlist, I can go a few days sometimes without checking my webmail (and thus seeing notification alerts of changes to pages on my watchlist). - or ask on my talk page,  which ensures I'm alerted immediately.
 * 2) I've been thinking - it might be best for me to create a sub-page under my own userpage for all our general discussions, leaving each of your sandbox talkpage just for key stuff relating to that one topic, with none of this general chit-chat. That way we keep all WP:AAU conversations in one place. What do you think? Something like: User talk:Nick Moyes/Adoption/BrucePL, perhaps.
 * 3) If you have Whatsapp on your mobile phone, I could email you my own mobile number and you would be very welcome to text me (for free) if you seek a speedy response. I guess it could potentially be useful to be able to video-chat through something extra-complicated, though I tend to think having a permanent record here of all help and guidance discussions is actually a very useful thing to be able to look back at.

 * Hi Nick. We can proceed however is easiest for you. I realize mentoring is extra work, so I want to minimize that. I installed Whatsapp messenger. Don't know how to use it yet... on the current page, I drafted an entry. Take a look. I did a CRVIO test with Earwig tool and got 0%. I think I did that correctly. Cheers, Bruce BrucePL (talk) 19:48, 24 March 2018 (UTC)
 * Hi, . Thanks for the notification. Does this mean you were emailed the deleted text? I don't think I heard anything more. I've found one problem which you might be able to address across a number of pages. I keep finding reference to 'spreading centres', but no definition of what these are. For example in Mid-ocean ridge (which you ought to link to with a lower case 'm') there's a wrongly emboldened link to ' oceanic spreading center, but no link is needed as it is currently a redirect back to itself at mid-ocean ridge. Are these totally synonymous terms? I'm assuming that they're not. But within that page I can find no exact explanation of what the term actually means, which I'm sure would be very helpful. Do you think the Mid-ocean ridge page merits a sub-heading entitled 'spreading centers', or a completely new page to explain the term? Never create new pages if you can cover a topic in one - and that could well apply to overlapping spreading centers and spreading centers, I suspect) Because you've linked to spreading centers on the Propagating Rifts page, you'll also need to remove that link until such time as there is a sub-section to wikilink to. (Am  I making any sense here?). Similarly, your new page on Overlapping spreading centers also has two links in the lead sentence back to MORs, which can be frustrating to readers.


 * I must confess to being a little out of my depth, trying to follow links to understand each term. I suspect this may be a case of you understanding a topic so well that you credit the general reader with more knowledge than they actually have, plus the lack (since 2008) of any explanation of what a spreading centre is. (I'm afraid I'm still unclear if a spreading center is the entire central line of the MOR; just a short section of the centre of an MOR between two transform faults, or an exact point in the centre of the MOR. (Somewhere I did read about new material being generated from a point in a tri-radiate manner in which one of the three arms is eventually lost, resulting in new plate material being produced from just two of those three arms, and becoming a feature with new plate material spreading apart by 180 degree - but I fear I've got lost somewhere whilst trying to come to grips with it all). So maybe a slight expansion is needed (or a more competent mentor!) When you start by saying ...seafloor features associated with faster rate spreading centers it leaves me wondering what a 'normal rate spreading center' means, and I can't then find enough links to explicitly tell me what spreading centers are let alone normal rate ones. Sorry to sound so stupid, but by trying to tease out my lack of comprehension I hope it might help you see that people like me need a bit more hand-holding.
 * I'm still having have a think about a separate page for communicating. Could be sensible. I'm also very new to Whatsapp, but do find it a nil-cost way to  contact some of my family members by text or video. Nick Moyes (talk) 16:11, 26 March 2018 (UTC)
 * Our Manual of Style asks us not to use capital letters except for proper names, so ...migration of Overlapping Spreading Centers (OSC) along the crest of a ridge. ought to become ...migration of overlapping spreading centers (OSC) along the crest of a ridge.


 * Thanks, Nick. I did receive the deleted texts by email from Dianaa. I wanted to cross check that I did not use the same or similar wording on my revised entries. As for spreading centers, thanks for pointing out the maze of confusion. I actually published an article that defines this. I think the way to handle it is to link to WP page Seafloor spreading, and upgrade that page a bit. I also did edits to add content to the MOR age. It needs a lot of work. I will correct syntax and grammar in the next few days also. BrucePL (talk) 17:43, 26 March 2018 (UTC)
 * That's good to hear. I hesitate to suggest it because of my lack of detailed knowledge, but to avoid any Conflict of Interest you could always either send me a summary to work on, or your article itself. I did find this that you appear to have written for EB. In haste, Nick Moyes (talk) 01:31, 27 March 2018 (UTC)
 * Ha; Brittanica. Totally forgot about that. That content is too sparse. Check what I inserted in Seafloor spreading under Spreading Center. BrucePL (talk) 19:05, 28 March 2018 (UTC)
 * On second thought, the EB is not bad, but I would write it differently now. Also, the EB article lacks sources. EB is also a bit redundant with content on the SFS page. Speaking of the SFS article, it has a section (Sea floor global topography: half-space model) that belongs under mid-ocean ridges. How to deal with that? BrucePL (talk) 19:15, 28 March 2018 (UTC)
 * Hi Bruce. I'm not sure quite what you mean by 'how to deal with that?' If you feel the whole section on the half space model is in the wrong page, be bold and move it - or feel free to discuss it on the article's talk page(s) first. I'm afraid my brain froze at that section, and didn't get past the few words, as I havea morbid fear of formulae, so am unsure how else to comment! I'm pleased to see you got a reply to your WP:TH question about linking to subheading within a page. Are you sorted on that now? If not, let me know what you want to achieve and I'll talk you through it. Nick Moyes (talk) 16:00, 29 March 2018 (UTC)

Thanks Nick. Yes, I figured out how to wlink to a section. Now I will fumble with Moving a section from Seafloor spreading page to Mid-ocean ridge page. I will ping you or Teahouse if I get stuck. Are you okay with the Prop Rift page? I addressed spreading centers so maybe I can move it to article space? BrucePL (talk) 17:24, 29 March 2018 (UTC)
 * OK, well done on the move - I saw your post at the TH. (I might just go and check whether you've made the attribution ok - if not I'll make a dummy edit for you in the edit summary). Right, I've challenged my brain and tried to wrap it around this short article. I think it's very nearly ready to go. I've dared to make a few suggestions to the wording which I've marked by either striking out words or adding them in CAPS. So please go though and decide if each one is helpful or just plain wrong!
 * You'll see I've also highlighted two alternative interpretations of one sentence which I'd just ask you to consider so as to ensure the best wording.
 * I'm still also bothered by the word 'faster rate spreading centers' in the lede. I ask myself "faster than what?" Now, I've read and re-read this inumerable times and, I still come away a little confused each time, as if there's something missing I haven't quite grasped. (Common with me, I'm afraid) So forgive my lack of knowledge if I say a few dumb things. Firstly, I still come away not having in my mind a picture of quite what propagating rifts actually are / what they would look like if I could drain the ocean and see them / if they have height / what their significance is and, in essence, why they're a notable geological feature and how their discovery impacts on our understanding of seafloor spreading. Now, these feelings might be simply because I'm struggling to grasp a heavily distilled scientific concept that you've spent half a lifetime working on. But it's worth me raising them as I guess some other users might also feel the same. So what small additions can you add that will help me understand better? I'll post this to you, go get a coffee, and come back and consider it further. So I might post again shortly.
 * Oh, you'll note I've added in a new section to Seafloor spreading - is there a better title for it? The idea was to shorten the lead and to lift up the contents to be higher on the page. I did the same for Overlapping spreading centers Is this OK?
 * Finally, I'm going a way for a week from Saturday, so have no idea if I'll have much time to go online to check for updates/questions from you. Make sure you ping me so I see any notifications, or use the WP:TH for anything you're stuck on. I can email you my mobile number if you feel you might want to message me for free via Whatsapp. I then come home and have been asked by from Wikimedia Foundation to do an hour long Skype survey/interview with him on support and help for new editors. So that sounds like fun. It's all go!  Nick Moyes (talk) 22:51, 29 March 2018 (UTC)


 * Great Nick! I'll dig in over the next week to cover these issues with OSC, PR, SFS. Have a presentation to prepare (you too sounds like). I'm in Talk now with the author of half-space on SFS User:Dan Gluck. He's reticent but I think I can convince him of the move. I am discovering that I could do editing full time!! BrucePL (talk) 16:20, 31 March 2018 (UTC)


 * Hi Nick. I made edits to PR and SFS following your advice. How does PR look now? BrucePL (talk) 23:45, 1 April 2018 (UTC)
 * Yep, Bruce, they're both looking better know. "along their trend" is a term that might possibly benefit from being explained in PR. If you're happy -or indeed unhappy - with the suggested changes I made in CAPS, it's fine to change or revert them back  to normal case, plus you might want to address the question I posed in the article about two  potential interpretations of the sentence.  I think then you should be OK to move it into mainspace whenever you're ready - not forgetting to ensure there's a short lead paragraph with the article title included in bold. Have spent today visiting Sutton Hoo from our holiday cottage. Might not be able to get back online every evening this week - but will try to keep an eye out.

Plans to edit
Hi! I am taking a 400 marine geology and geophysics class and I plan to edit this page. Some plans I have in mind are as following:

1) I realized that there are many other terms such as "ridge propagation", "ridge jumps", that are sometimes used interchangeably with "propagating rift". Hence I plan to create a "Terminology" section to explain how these terms are used for the same thing and how they could sometimes be used differently under different context.

2) I also plan to work on the mechanisms that cause propagating rifts. Some of the mechanisms I have found so far include fracture mechanics, hot-spot interaction, change in plate motion etc.

3) Besides, I plan to have a "geometry" section to better define the identification of propagating rifts.
