A volcanic arc is a chain of volcanoes formed above a subduction zone, where one tectonic plate is forced under another. These arcs typically develop parallel to the trench created by the subduction and are a direct result of the melting of the descending plate, leading to magma formation that rises to the surface. Volcanic arcs play a crucial role in shaping mountainous regions and can significantly influence the geology and ecology of the surrounding areas.
