Respuesta :
Volcanic arcs form on plates that are subducting.
What are Volcanic arcs?
A volcanic arc is a belt of volcanoes that developed above an oceanic tectonic plate that is subducting, with the belt being arranged in the shape of an arc from above. Ordinarily, volcanic arcs lie farther away from the subducting plate than the trench, parallel to an oceanic trench. The oceanic plate is largely made up of hydrous minerals like micas, amphiboles, and serpentine minerals, which are saturated with water.
What boundaries cause volcanic arcs?
Divergent and convergent plate boundaries are the two types of plate boundaries that are most likely to result in volcanic activity. Separate Plate Boundaries The diverging border causes the separation of tectonic plates.
