GEOLOGY

Detailed explanation-1: -Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.

Detailed explanation-2: -Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Divergent Plate Boundaries At a divergent boundary, tectonic plates move apart from one another.

Detailed explanation-3: -Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.

Detailed explanation-4: -Earthquakes and volcanoes usually occur at the edges of tectonic plates. It is much less likely for these to occur in areas that aren’t near plate boundaries, as the movement of the plates causes these events. Some volcanoes can occur in hot spots within plates but these are less common.
