island chains
Sequential oceanic landmasses
Island chains are groups of islands arranged in a roughly linear sequence, typically formed by volcanic activity along tectonic plate boundaries or over geological hotspots: the Aleutian island chain, the Hawaiian island chain.
The term emphasizes geographic continuity—islands close enough to form a recognizable series rather than scattered archipelagos.
