Climax - the "high point" of a story in which the major conflicts erupt in some kind of final showdown (fight, argument, violent or physical action, very tense emotional moment...); at the end of the climax, the "winner" will be clear (there is not always a winner!). This is the point in the story where something CHANGES.
Resolution/Denouement - where everything ends; the reader may have some sense of "closure" or may be asked to think about what might come next; in fairy tales, the Happy Ending; in some novels, you will read about the characters many years later.
