Physical boundaries are natural features like mountains or rivers that separate regions, whereas political boundaries are man-made lines denoting the borders of countries or territories established by governments. Physical boundaries are determined by nature, while political boundaries are decided by human agreement and often subject to change.
Wars and political conflicts can impact civilians depending on the country they live it. If you live in a country at war, you are subject to the dangers, if your country does not proactive civil rights, you may be punished for your political beliefs.
A political map serves this purpose as opposed to a physical map which shows features of geography, such as mountains
a boundary that is man made.
Fabulous question! Sometimes political boundaries follow rivers, mountain ranges or other natural boundaries. If the land is very flat it is typical to have them follow a surveyors line. Politics, agreements, treaties, wars, technology and geography tell the history of state and national boundaries.
