The term that refers to lands that are covered and uncovered by the ebb and flow of the tide is "tidelands." Tidelands specifically describe the areas of land that are directly influenced by tidal movements, where water levels fluctuate with the changing tides. This includes both the zones that are submerged at high tide and the areas that are exposed at low tide.

Tidelands are important for various ecological reasons, as they often serve as habitats for diverse species and can play a critical role in the overall health of coastal ecosystems. They also hold legal significance in many jurisdictions regarding property rights and regulatory frameworks.

The other terms listed serve different specific purposes. Wetlands refer to areas where water covers the soil, either permanently or for varying periods, but not necessarily tied to tidal influences. Floodplains represent flat areas adjacent to rivers and streams that are susceptible to flooding but are not dictated by tides. Coastal lands are a broader category that encompasses all lands adjacent to an ocean or sea, which may include beaches, cliffs, and other landforms, but they do not specifically relate to the tidal action that defines tidelands.
