As earthquakes do not occur in magma, this region cannot be a chamber completely filled with magma but rather a heterogeneous … The ultimate source of magma is partial melting of rock in the upper mantle and lower crust. This produces magma that is less dense than its source rock. For example, a granitic magma, which is high in silica, has a density of 2.4 Mg/m , much less than the 2.8 Mg/m of high-grade metamorphic rock. This gives the magma tremendous buoyancy, so that ascent of the magma is inevitable onc… how to overlay images in word
