What is the name of the chain of volcanoes that form at an oceanic to oceanic plate boundary?
When there is oceanic-oceanic convergence, one layer of oceanic lithosphere is subducted. This not only introduces water, which lowers the melting temperature of the asthenosphere, but can create an island with a volcano. This occurs when the hot magma rises from the subduction zone and build up in size. This would not have any specific name. If the volcano was situated on a hot spot, however, it would form linear island chains.
