Explanation:

Slide transitions are the animation-like effects that occur when you move from one slide to the next during a presentation. You can control the speed, add sound, and customize the properties of transition effects. Slide transitions are the animation effects that are applied to whole slide whereas animation effects are applied to objects (text, shape, picture etc.) on a slide. For a slide you can have only one transition effect while each object on the slide can have multiple animation effects.
