A map that shows the boundaries of countries, regions, and states is called a political map.

Here's why:

* Political refers to the organization and governance of a territory.

* Political maps focus on human-made boundaries and divisions, rather than physical features like mountains or rivers.

Other types of maps exist, but they focus on different aspects:

* Physical maps: Show physical features like mountains, rivers, and oceans.

* Thematic maps: Highlight a specific theme, like population density, climate, or natural resources.

So, if you're looking for a map that clearly shows the borders between different political entities, you're looking for a political map.
