Which boundary leaves a mark on landscape or culture after ceasing to exist as a political boundary?

• A. Antecedent boundary
• B. Natural boundary
• C. Geometric boundary
• D. Relic boundary

Answer: (D)

A relic boundary is about a former political border whose line is no longer active, yet its presence lingers in the land and in people’s memory. When a boundary dissolves, the trace it left can remain in how the landscape is shaped, in the names of places, in old border markers or fortifications, and in the cultural or social practices of communities that were divided by it. That lasting imprint is what distinguishes a relic boundary: it has ceased to function as a political divider, but it continues to influence geography and culture.

In contrast, natural and geometric boundaries are defined by physical features or straight lines, and while they can shape landscapes, their identity isn’t about a former political division leaving a cultural memory after the boundary ends. Antecedent boundaries are boundaries that existed before settlement and often persist or influence later borders, but the specific idea here is about a boundary that no longer exists yet still marks the land or culture.
