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.
Stack â Further backward erosion into a headland resulting in a collapsed arch and the formation of a sea stack. An example of this is at Botany Bay in Kent (see Bay, for picture). Coastal Landforms Tombolo â Sea ward deposition of sediment linking the mainland to an island.We have no tombolo within the south east boundaries; however good examples include Holy Island, Northumberland, St Michaelâs Mount, Cornwall, and the Isle of Portland.oastal Landforms Beach â an area of coastal sediment accumulation at the land-sea boundary. The beach is the first line of defence for coastal protection. The beaches along our coastline are characterised by shingle, sand, shell and shale. Delta â Deposition of fluvial sediments into the coastal waters.
