Many island chains around the world are formed as a result of volcanism, which is the process of magma from the earth's. The indonesian island chain was created by volcanism caused by one tectonic plate sliding beneath another, known as subduction. In short, island chains form when an underwater volcano erupts many times over millions of years;

In this investigation, students analyze hawaiian and alaskan seamount/island chain maps and data tables, plus a demonstration to develop an explanation to the phenomenon: Many of the islands in the caribbean were actually formed as a result of the subduction of oceanic crust of the atlantic plate under the caribbean plate in the lesser. Island chains, such as the hawaiian islands, were formed as a result of hotspot volcanism, where stationary mantle plumes create volcanoes as tectonic plates move over. Many island chains were formed as a result of volcanism.
How are archipelagos formed ARCHIPELAGO
