many times you have a little vagueness about sizes and time, if you can find more specific information, that would add a lot.

It could use some pictures for at least the location of the PFR. intro --'10,000 km long' instead of length -- last line- comma after pacific ridge is gone

edit the spacing between subheaders

in the 'characteristics' part, --you can simply say PFR is a divergent boundary and hyperlink the 'divergent boundary' to its wikipedia page. you could also hyperlink other scientific terms to create a better flow if one needs to know something more.

--rephrase 'from this boundary....new seafloor'. something like "as magma comes up from the ridge, new sea floor is formed/created".

-- usually articles use "about" for approximation instead of "about". But it's completely okay to say 'around 20 mn yrs ago' as well.

--change north america to north american plate

end(?? could use another word like subduction) of PFR

--again use hyper link for the global and local oriented systems.

--use only 'million years ago' or 'MA' throughout the article for consistency.

--could mention the current spreading rate

-- oxford comm can be used in this sentence "ago;around the same time that a significant"

add a subheader for the references.

link # 2, 5, 6, 9 for references do not lead to the valid source page.

Good break-up of sections. Good flow from one topic to another. Good amount of references. Overall good article, just a few changes.

Bold your topic in the first line, Pacific Farallon Ridge.

Your first sentence says the PFR "was" a spreading ridge, yet later you go on to say that it is inactive. I think you should change your first sentence to state that its inactive. By the use of woring "was a spreading ridge" it sounds like its no longer there. Possibly change it to say "was an active spreding ridge during..."

I would put the time frame of when the 'late cretaceous' is considered in parenthesis after 'during the late cretaceous (xtime-xtime).

Rearage first sentence to read..."in length, separating the Pacific plate, to its east, from the Farallon Plate, to its west.

Can any of you words be links to other articles? Such as Cretaceous, Pacific Plate, Farallon Plate, etc.(this applies to the whole article, but you only link the term once)

I would indicate where along the North American plate the 'eventaul collision happened' or where it subducted in one of the last two sentences of the 'overview' section.

To many spaces between the 'Overview' section and the 'Characteristics' section. (or not enough between the other two) either way just make them consistant.

Re-write first sentence of 'characteristics' to read "As a spreading ridge (no comma) the PFR is a divergent plate boundary, meaning the Pacific Plate and North American Plate are spreading away from each other, creating a ridge in the space between them."

Re-write second sentence..."From this boundary magma rises, which cools..."

The PFR "was thought to be a particularly productive spreading ridge"...not a good sentence. It rises questions such as, thought by whom? what did others/opposition think? is this a debatable topic? ect.

Change sentence to"...of all oceanic lithoshpere for the past 83 million years."

Comma needed in the 4th sentence of "characteristics" after "..million years ago, around the same.."

Looked at other wikipedia pages and they capitalized Plate. IE North American Plate, Farallon Plate, Pacific Plate.

Do you know how much a "significant portion" is? Half? 3/4? Is there a reference for this?

It would be good if you could get a picture of all the little microplates.

You could add lat and long of the ridge to the overview section.

The last section title is confusing. I thought "End" meant orientation along the ridge, not how it ended its existence.

Sometimes you refer to the ridge subducting under the North American Plate, and other times its North America. I think you need to be consistent.

Re-write to read "The initial collision of the ridge with the North American Plate, roughly 26 million years ago, ..."

Take out the "fianlly" in the second to last sentence.

Write out Ma to keep it consistent with the rest of the article (or change all the others)

Expalin what you mean by "essentially replaced"...to much uncertainty.

Add a notes section/reference section to create a space between your article and the references.
