A bay is a body of water partially enclosed by land, typically with a wide mouth opening into the ocean or another larger body of water. Bays also provide important habitats for marine life and serve as shipping routes and centers of economic activity.
Bays can vary in size and shape, ranging from small indentations along coastlines to large expanses of water bordered by peninsulas or capes.
They are often characterized by calm waters, making them ideal for harbors, ports, and recreational activities such as boating and swimming.
