land border

A land border is a geographical boundary separating two neighboring countries or jurisdictions on land. It serves as a designated line where cross-border movement is regulated by laws and border controls, such as customs, immigration checks, and security measures. Land borders help define territorial sovereignty, manage trade and travel, and prevent illegal activities. They can vary in size and complexity, ranging from straight, simple lines to more complex, irregular boundaries influenced by history or geography. Overall, land borders are crucial in defining national territories and maintaining legal and security frameworks between nations.
