Final answer:
Divergent plate boundaries result in more explosive volcanism as they create a gap for magma to rise to the surface.
Step-by-step explanation:
Divergent plate boundaries are the type of boundaries that result in more explosive volcanism. These boundaries occur when tectonic plates move apart, creating a gap where magma can rise to the surface. The reduced pressure conditions in the underlying mantle allow for the production of magma, which leads to explosive volcanic eruptions.
