Final answer:The steps ofvolcanic island arc formationare as follows: 1. Asubduction trenchforms where the subducting plate bends downward into the mantle. 2. Magma, created by flux melting of the mantle, rises through the overriding plate. 3. Lava erupts onto the surface, forming volcanoes. 4. An accretionary prism begins to form.Explanation:Asubduction trenchforms where the subducting plate bends downward into the mantle.Magma, created by flux melting of the mantle, rises through the overriding plate.Lavaerupts onto the surface, forming volcanoes.Anaccretionary prismbegins to form.Volcanic island arcs are formed as a result of the subduction of an oceanic plate beneath another oceanic plate or a continental plate. The process begins with the subduction of one tectonic plate beneath another, leading to the formation of a subduction trench. As the subducting plate sinks into the mantle, it generates intense heat and pressure that cause the mantle to melt partially. This melted material, known as magma, is less dense than the surrounding rock, so it rises through the overlying plate.The magma generated through this process can eventually reach the surface and erupt as lava, forming volcanoes. The accretionary prism, made up of sediment and material scraped off the subducting plate, accumulates in the subduction trench area. This contributes to the growth of the volcanic island arc over time. The volcanic activity is a result of the movement of the magma from the subduction zone to the surface, leading to the formation of a chain of volcanic islands or an island arc.Learn more aboutvolcanic island arc formationhere:brainly.com/question/28522384#SPJ14...
