All General Island and Archipelago Concepts

This group collects the Islands and Archipelagos subcategory's members that are general landform definitions rather than one specific named place: the islet, skerry, tidal island, river island, barrier island, sand island, pseudo-atoll, presque-isle, sound and gat as classes of coastal and fluvial landform. Each entry explains what the term means and how the feature type forms, so a reader can look up the vocabulary the subcategory's named entries use rather than finding another named archipelago here; these entries were identified by their own definitional opening, stating what the term is rather than describing one place.
