Isthmus

An isthmus is a slender strip of land that bridges two larger landmasses, typically separating bodies of water. These geographical features play crucial roles in transportation, trade, and ecology. Notable examples include the Isthmus of Panama, connecting North and South America, and the Isthmus of Suez, linking Africa and Asia. Related landforms include tombolos, which are isthmuses formed by sand deposition, and straits, the aquatic equivalent connecting larger water bodies.
