What plate boundary forms aVolcanic islands
Answers

Volcanic islands typically form at convergent plate boundaries, specifically at subduction zones where one tectonic plate is forced beneath another. When an oceanic plate subducts beneath another oceanic plate, it leads to the formation of a volcanic island arc. A well-known example of this is the Aleutian Islands in Alaska and the Japanese archipelago.
Volcanic islands can also form at divergent boundaries, where tectonic plates are pulling apart, allowing magma to rise and create new land, such as the islands of Iceland, which is situated on the Mid-Atlantic Ridge.
In summary, volcanic islands can form at both convergent (subduction zones) and divergent plate boundaries, but the most common association is with convergent boundaries.
