Landforms Vocabulary. Archipelago â a group of islands or a cluster of islands usually found in the open sea. They can be formed by erosion but most often occur as the result of volcanic activity. Fiji, Bora Bora, the Florida Keys, and even the entire nation of Japan are examples of archipelagos.
Barrier island contrasted with other coastal landforms. Barrier islands are a coastal landform and a type of dune system that are exceptionally flat or lumpy areas of sand which form by wave and tidal action parallel to the mainland coast.They usually occur in chains, consisting of anything from a few islands to more than a dozen.he length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends and basement controls. Chains of barrier islands can be found along approximately thirteen percent of the world's coastlines.
