The geographic feature defined as a narrow strip of land connecting two larger land areas is called an isthmus. Isthmuses typically form land bridges that have significant geographical and strategic importance, often facilitating movement of people, animals, and goods between two larger regions. A well-known example is the Isthmus of Panama, which connects North America and South America and is home to the Panama Canal, a crucial waterway for international maritime trade. Isthmuses can also encourage cultural exchanges and biodiversity as they serve as biological corridors for various species due to their unique habitats.
