<u>Question: Why do political boundaries change?</u>
<u />
Answer: <u>These lines, more often called borders, are created by people to separate areas governed by different groups. Sometimes, political boundaries follow physical boundaries, but most of the time you can't see them. Most maps show political boundaries. Political boundaries change over time through wars, treaties, and trade.</u>
