WebApr 15, 2024 · Why does magma form at a convergent boundary? 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. WebThe new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving away from each other, we call this a divergent plate boundary.

WebMagma formed from the melting of lithosphere along convergent plate boundaries is contaminated by water and country rock. Both of these increase the viscosity of the magma which is considered highly viscous. What does magma viscosity have to do with the grand scheme of things? Well the more viscous a magma, the harder it is to flow.

Magma forms when a) The descending plate heats up and melts in the subduction zone. b) Friction from earthquakes causes rocks in the descending plate to melt. c) Water from the descending plate is added to rocks of the overriding plate. phogs invisible ink

"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.
