Answer:
Hello. You have not attached the map to which this question refers, which makes it impossible for your question to be answered. However, I can help you by showing that the political map can be used by a historian who wants to study the distribution and division of Roman society within Roman territory.
Explanation:
A political map is used when a stylist wants to analyze the administrative division of a territory, showing the border of that territory with neighboring territories and also showing the internal borders that show the divisions within the territory.
In this case, we can say that a historian would use a political map to analyze the geographic distribution and population concentrations of Roman civilization.
The mid-ocean ridges are elevated above the surrounding seafloor because Ridge rocks are hot and therefore of relatively less dense than adjacent cooler oceanic crust.
I hope this helps you! :)
