A gulf is a large body of water that is partially surrounded by land, with a narrow mouth opening into the ocean or sea.
Gulfs are typically larger and deeper than bays, often extending farther inland and characterized by a wider expanse of water. They can vary in size and shape, from smaller indentations along coastlines to vast, expansive bodies of water bordered by multiple countries or regions.
Gulfs play important roles in global trade, marine transportation, and the ecological balance of coastal ecosystems.
