Which term describes a type of political border that follows a prominent physical feature of the landscape, such as a river, mountain range, or desert?

💡 Explanation:

A natural border, also known as a physical or physiographic border, utilizes distinct geographical features like rivers, mountains, or deserts to define the boundary between two political entities. Geometric borders are typically straight lines, antecedent borders existed before significant cultural landscapes developed, and superimposed borders are drawn over existing cultural landscapes.
