A geographical boundary is a defined line that separates different areas, regions, or countries. These boundaries can be natural, such as rivers, mountains, or lakes, or they can be artificial, created by human decisions, like political borders. They help to establish jurisdiction, governance, and ownership of land. Geographical boundaries play a crucial role in various fields, including politics, environmental science, and urban planning. They influence cultural identities, resource distribution, and economic activities. Understanding these boundaries is essential for effective management of land and resources, as well as for fostering cooperation between neighboring regions.
