Tidal plains are flat, low-lying areas that are covered and uncovered by the rise and fall of the tides. Synonyms for this term include tidal flats, intertidal areas, and mudflats. These areas are formed by the constant movement of water, which deposits sediments and creates a unique ecosystem with diverse plant and animal life. The term also includes salt marshes, which are wetlands that are periodically flooded by seawater and provide important habitat for birds and fish. Other synonyms for tidal plains are floodplains, estuaries, and delta plains. These areas are important for coastal communities, as they provide crucial habitat for marine life and serve as protection against storm surges and sea level rise.
