What does an author use to control the pacing of a story?

An author can control the pacing of a story by changing the sentence structure or how quickly events unfold in a story.

Pacing is a tool used in literature intended to control the speed and rhythm at which a story is told and the readers are pulled through the events. It refers to how fast or slow events in a piece unfold and how much time elapses in a scene or story. Pacing may be employed in order to to show characters aging as well as  the effects of time on story events.
