Yes, when there are enough items in the pending edit queue a link appears up in the bar at the top (the page can also be reached via the 10K mod tools). A user can then browse the pending edits and approve or reject the ones they review (or ignore them if they cannot make a decision). It takes two votes for a pending edit to be either rejected or approved.

in answer to your comment... I'm not quite sure I understand the question you're asking now but I'll still try to answer it. You can read more about Closing/Open votes here: Cast close and reopen votes
With deletion votes there is a vote number threshold that must be met before the question is deleted, that threshold depends on the upvotes of the question (I'm not sure if the number of answers is also factored in). For example, this question Why is Git better than Subversion? still requires another 64 votes to delete it - in reality it will probably never cross that threshold.
