Question

Why do most volcanoes occur at plate boundaries and which two types of boundaries are most common?

Answer 1

A divergent plate boundary and convergent plate boundary

Step-by-step explanation:

Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; and

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.
