Which of the following would be good visual aids for a speech on the United States' geographical features? Select all that apply. a whiteboard sketch of Europe and the U. S. to show size comparisons
a slide show illustrating the formation of the mountainous regions in the U. S.
a large color-coded map showing the different geographical regions
an overhead transparency listing all the important geographical landmarks in the U. S.

The option that is a good visual aid for a speech on geographical features is:

B. a slide show illustrating the formation of the mountainous regions in the U.S.

Explanation:

All four options are related to geography somehow. However, we must look for the one that is more efficient in terms of illustrating geographical features. Features, when it comes to geography, are related to landforms. For example, mountains and canyons are geographic features.

With that in mind, we see that letter B is the best option. Letter A concerns the sizes of different continents; letter C concerns the different regions; letter D is related to landmarks. Letter B is, in fact, the only visual aid that will help the audience visualize geographical features.
