At convergent boundaries magma is formed where water from a subducting plate acts as a flux to lower the melting temperature of the adjacent mantle rock. At divergent boundaries magma forms because of decompression melting. Decompression melting also takes place within a mantle plume.

WebMagma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. Two plates … WebAnswer (1 of 2): “Formed” is the wrong concept. Magma is always present everywhere beneath us at varying depths. At divergent boundaries and convergent subduction zones, it is closest to the surface resulting in some magma ejecting onto the surface in one form or another.

4.1 Plate Tectonics and Volcanism – Physical Geology

WebSep 27, 2024 · How do volcanoes formed along convergent plate boundaries? Volcanoes form along convergent plate boundaries because the two plates are slowly moving towards each other. This forces the molten rock on the two plates to move and cool. This in turn creates a volcano by the combination of the hot rock and the pressure from the two plates. WebApr 16, 2024 · What features form as subduction produces magma? Volcanic arcs form parallel to subduction zones. As one plate descends under another plate, it heats up and becomes magma. The magma will rise through the crust until it reaches the surface. This magma creates a chain of volcanoes or a volcanic arc near the boundary of the top plate.
