There are three settings where volcanoes typically form: constructive plate boundaries. destructive plate boundaries. hot spots. Volcanoes do not typically occur at transform boundaries. One of the reasons for this is that there is little or no magma available at the plate boundary. Ver mais At constructive plate boundaries, the tectonic plates are moving away from one another. The Earth’s crust is pulled apart to create a new pathway for rising hot magma to flow on to the surface. Volcanoes can … Ver mais Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other.
