Final answer:
Political maps change due to natural events, religious affiliations, and political instability, while sports rivalries do not have a direct impact.
Step-by-step explanation:
The factors that contribute to why political maps change are natural events, religious affiliations, and political instability. Sports rivalries, on the other hand, do not directly impact political map changes. Natural events, such as earthquakes or hurricanes, can lead to changes in borders or the creation of new land formations. Religious affiliations can influence political boundaries if different groups have conflicting territorial claims. Political instability, including wars or regime changes, often result in redrawing of political boundaries.
