An archipelago (/ɑːrkɪˈpɛləɡoʊ/ ( listen) ark-i-PEL-ə-goh), sometimes called an island group or island chain, is a chain, cluster or collection of islands, or sometimes a sea containing a small number of scattered islands. The word archipelago is derived from the Greek ἄρχι- – arkhi- ("chief") and πέλαγος – pélagos ("sea") through the Italian arcipelago. In Italian, possibly following a tradition of antiquity, the Archipelago
Archipelago
(from medieval Greek *ἀρχιπέλαγος and Latin archipelagus) was the proper name for the Aegean Sea
Aegean Sea
and, later, usage shifted to refer to the Aegean Islands
Aegean Islands
(since the sea is remarkable for its large number of islands).

Types[edit] Archipelagos may be found isolated in large amounts of water or neighbouring a large land mass. For example, Scotland
Scotland
has more than 700 islands surrounding its mainland which form an archipelago. Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots, but may also be the result of erosion, deposition, and land elevation. Depending on their geological origin, islands forming archipelagos can be referred to as 'oceanic islands', 'continental fragments', and 'continental islands'.[1] Oceanic islands are mainly of volcanic origin. Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. Finally, sets of islands formed close to the coast of a continent are considered continental archipelagos when they form part of the same continental shelf so islands are just exposed continental shelf. Indonesia, Japan, Taiwan, the Philippines, New Zealand, Maldives, British Isles, the Bahamas, Greece, the Florida Keys, Hawaii, the Polynesian islands, the Canary Islands
Canary Islands
and the Azores
Azores
are all examples of well-known archipelagos. The largest archipelagic state in the world by area and population is Indonesia.[2] See also[edit]
