Talk:Divergent boundary

message: Illustrations and images: Though the images and illustrations in the article are helpful, they are far from sufficient (in terms of quantity, at least). The text states: "A sea floor map will show a rather strange pattern of blocky structures that are separated by linear features perpendicular to the ridge axis"; instead of forcing the reader to visualize this image independently, a (bathymetrical) map of the seafloor could be included. The image provided of the Álfagjá Rift Valley is a nice visual aid, but the satellite image of a MOR (e.g. the East Pacific Rise) might be more useful to have, in correspondence with the text. It would also probably be a good idea to add an illustration of a divergent boundary with labels (especially for the Earth's layers) to accompany the first illustration on the page.
References:  Only one citation is made within the entire article. The following could have definitely been cited:
* "Over millions of years, tectonic plates may move many hundreds of kilometers away from both sides of a divergent plate boundary." Do we assume this?
* "The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots." Thought by whom, originally?
* "The hot spot which may have initiated the Mid-Atlantic Ridge system currently underlies Iceland which is widening at a rate of a few centimeters per year." How do we know?!
* "Scientists had been studying polar reversals and the link was made by Lawrence W. Morley, Frederick John Vine and Drummond Hoyle Matthews in the Morley–Vine–Matthews hypothesis." Why not cite a work that can confirm this? Or, better yet, the works of these people?!

I agree. This whole plate tectonics thing is kind of confusing. I'd rather learn something more useful.
I got to do a project for school. Thats the only reason I'm here

message: I changed this sentence in the lede:
"In plate tectonics, a Divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other."
to read 'two' instead of 'five' -- any particular, individual divergent boundary will involve two (possibly three) plates, but in general only two. If this sentence was meant to convey that there are, at the moment on Earth only five plate boundaries that are divergent, than it needs a separate sentence to say so (with citation of course). 71.139.1.243 (talk) 15:51, 13 January 2010 (UTC)

message: It may be worthwhile to add a separate section in this article going deeper into the formation of new oceanic crust at Mid-Ocean Ridges and the resulting ophiolite sequences that provide substantial geologic records of plate movements.
This article also needs a serious fortification of its sources. Much of the facts in here have no references for people to verify.Oceanfr (talk) 06:46, 8 April 2017 (UTC)

message: * With only one referenced publication, this article lacks to provide a comprehensive, unbiased overview of subject matter; this article also lacks sufficient citation of provided reference.
* It might be worth providing a reference map of Earth showing locations of divergent boundaries and how they are situated among other major plate boundaries.
