What is an isthmus?

An isthmus is defined as a thin strip of land that connects two larger land masses. This geographical feature is characterized by its narrowness, which is typically bordered by water on both sides, allowing for the connection of two larger regions. It often serves as a critical passageway for transportation and trade, making it significant in both historical and modern contexts. For example, the Isthmus of Panama connects North America and South America and serves as a crucial route for maritime trade through the Panama Canal. Understanding the definition and examples of isthmuses helps in grasping their importance in geography and global navigation.
