The term for a narrow body of water between two land masses is a strait. Straits are significant geographical features that often serve as natural waterways for maritime navigation and trade. They can vary in size, depth, and width, and some of the most notable straits include the Strait of Gibraltar and the Strait of Magellan. Straits can also serve as important ecological zones, supporting rich marine biodiversity and acting as critical habitats for various species. Due to their strategic locations, they hold historical, economic, and political importance.
