What is the definition of a bay?

A bay is defined as a body of water that is partially enclosed by land and typically smaller than a gulf. This geographical feature is characterized by its shape, which allows it to provide shelter from waves and winds, making it an important area for marine habitats and human activities such as fishing and boating. The partial enclosure contributes to distinct ecological zones within the bay, where freshwater from rivers may mix with saltwater, creating unique environments. Bays often serve as critical areas for commerce and recreation, making the understanding of their definition significant in social studies, particularly in topics related to geography and human-environment interaction.
