Final answer:
Antecedent boundaries are established before major settlement in a territory. The 49th parallel border between the United States and Canada is an example of an antecedent boundary.
Step-by-step explanation:
The borders that are established before major settlement by people in a territory are called antecedent boundaries. These boundaries are often based on physical features like rivers or mountains, and they can have a significant impact on the development and management of the territory.
For example, the 49th parallel border between the United States and Canada is an antecedent boundary. It was established before significant settlement in the area and is now a well-defined division between the two countries.
