This group collects the Landform Concepts subcategory's members that name and define coastal and shoreline landforms: the general vocabulary of capes, headlands, cliffs, spits, tombolos, lagoons, estuaries, straits, firths, tidal flats and raised beaches that a coastline builds through wave, tide and longshore action, plus the narrower channels, inlets and narrows that connect open water to sheltered water. Every entry here is a definitional landform-type article rather than one named place, explaining what the term means and how the feature forms so a reader can look up the vocabulary this atlas's named coastal entities use elsewhere.
