Final answer:
Explosive volcanoes are found on the lower plate at a convergent boundary.
Step-by-step explanation:
Some of the most explosive volcanoes are found on the lower plate at a convergent boundary. These are known as subduction zone volcanoes, where one tectonic plate is forced beneath another. The subducting plate carries water and other volatile substances into the mantle, leading to the formation of magma and eventually explosive eruptions.
