Question

Quizplus · Accepted Answer

Convergent plate margins are characterized by volcanoes that include basalt, andesite, dacite, and rhyolite. This is because convergent plate margins occur where two plates are moving towards each other, causing one plate to subduct beneath the other. The subducting plate carries oceanic crust, which is denser than the overriding plate, into the mantle. As the oceanic crust descends into the mantle, it melts and creates magma that rises up to the surface to form volcanic arcs. The composition of the magma depends on the temperature, pressure, and composition of the mantle and crust that the magma is derived from.
