Which term best describes 'waters that are subject to the ebb and flow of the tide'?

The term that best describes 'waters that are subject to the ebb and flow of the tide' is coastal waters. Coastal waters refer to the areas of ocean and sea that are adjacent to the land and are influenced by tidal movements. These waters experience regular fluctuations in water levels due to the gravitational pull of the moon and sun, which leads to the characteristic rise and fall of tides.

Inland waters typically refer to lakes, rivers, and other water bodies that are far removed from the ocean and not primarily influenced by tidal movements. Navigable waterways can include both tidal and non-tidal rivers but do not specifically denote those affected by tides. Great Lakes waters are a specific category of inland freshwater lakes that are not subject to tidal influence as they are not connected to oceanic tides. Thus, coastal waters is the most appropriate term.
