Ebb tide is a term used to describe the period of time when the tide is receding away from the shore. There are a number of synonyms that can be used to describe this process, including low tide, outgoing tide, falling tide, and ebbing tide. Other related terms include slack water, which refers to the period between high and low tides when the water is relatively still, and tidal range, which describes the difference between high and low tides. These terms are useful for understanding the patterns of the tides and the ways in which they affect coastal environments and communities.
