More superficially, articles themselves tend to be lengthy and they have long, descriptive titles (no clickbait!). Their purpose is to inform an already-interested professional audience, therefore, they don't have flashy layouts or graphics.
If an article is peer-reviewed, other experts in that field have critically reviewed the article for content (looking at the research process, the conclusions vs the evidence, and so on). They may make suggestions for revision to the process or at least the documentation ("revise and resubmit") before the article is allowed to be published.
This is different from an article being reviewed by a single editor who looks for basic fact-checking and style adherence, and very different from a self-published website popping out a new post.
They can be! Note that a scholarly book is not just any old nonfiction title, but they can be a little harder to distinguish sometimes.
Yes, and this can be a good -- no, great thing, because books can spend some time giving you background info that a much shorter article cannot.
Generally speaking, for most of the research you're doing at this lower-division undergrad level, you're reading to get information on your topic with enough context to not misrepresent anything. It is natural to not read a book cover-to-cover in this context. E-books make this even easier with the search-inside functions!
