How does subduction trigger melting? A. Flux melting of the asthenosphere above the subducting slab creates a rising melt. B. The subducting slab is made of felsic minerals and therefore

melts at lower temperatures. C. The overriding slab insulates the subducting slab, increasing temperature and causing melting. D. The down going slab melts as it reaches hotter temperatures deep in the Earth.
