Question

which factor had the most impact on the creation of the borders shown on the map above? climate zones ethnic divisions physical geography mountain barriers

Explanation:

To determine the factor with the most impact on border creation, we analyze the options. Ethnic divisions relate to cultural/ethnic groups, while climate zones, physical geography, and mountain barriers are physical factors. However, in many historical and political contexts, ethnic divisions (cultural - social factors) often play a crucial role in border creation as states or regions may be formed along ethnic lines. Physical factors like geography or climate can also matter, but ethnic divisions are a key social - political factor in border delineation, especially in regions with ethnic diversity. Since the question is about border creation impact, ethnic divisions (a sub - area of Social Science, specifically related to Sociology/Politics) is the most probable as it deals with human - made or socially influenced borders.

Ethnic divisions
