GEOLOGY

Detailed explanation-1: -Composite volcanoes, also known as stratovolcanoes, are found on convergent plate boundaries, where the oceanic crust subducts beneath the continental crust.

Detailed explanation-2: -Stratovolcanoes typically form at convergent plate margins, where one plate descends beneath an adjacent plate along a subduction zone.

Detailed explanation-3: -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.

Detailed explanation-4: -Stratovolcanoes tend to form at subduction zones, or convergent plate margins, where an oceanic plate slides beneath a continental plate and contributes to the rise of magma to the surface.

Detailed explanation-5: -The Aleutian volcanoes are an island arc formed at an ocean-ocean convergent boundary. The Cascade volcanoes are a continental arc formed at an ocean-continent convergent boundary.
