Web16 de abr. de 2024 · A volcanic island arc is formed when two oceanic plates converge and form a subduction zone. The magma produced is of basaltic composition. A continental volcanic arc is formed by subduction of an ocean plate beneath a continental plate. The magma produced is more silica rich than that formed at a volcanic island arc. Web26 de set. de 2024 · The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes.
