What type of animation allows elements to appear on a slide one at a time?

Entrance animations are specifically designed to control how elements appear on a slide. They allow for the gradual introduction of objects such as text, images, or shapes, making the presentation more engaging and effective. By using entrance animations, presenters can focus the audience's attention on one element at a time, enhancing comprehension and maintaining interest.

This approach is useful in guiding the audience through the content step by step, as instead of overwhelming them with all information at once, it reveals each point in a controlled sequence. This can also help in emphasizing key messages, ensuring that important information gets the attention it deserves.

While exit animations deal with how elements leave the slide, emphasis animations are meant to highlight or draw attention to elements already present on the slide. Distraction animations are not a recognized category in professional presentation design and may create unnecessary movement that could divert attention away from the message being conveyed. Thus, entrance animations are the ideal choice for presenting elements one at a time.
