GEOLOGY

Detailed explanation-1: -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-2: -At a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.

Detailed explanation-3: -Answer and Explanation: Most earthquakes and volcanoes happen at plate boundaries because in between plates there is a lot of activity, meaning tectonic plate movement (convection forces that rock deformation and construction of faults and fractures).

Detailed explanation-4: -About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Detailed explanation-5: -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.
