WebIsland arc volcanoes occur when one plate descends, or subducts, under another plate. Subduction allows water from the subducting plate to be driven upward, off the subducting plate and into the mantle wedge. This lowers the melting point of the mantle, and it melts to form magma. This magma will rise and leak into the crust forming a volcano. WebOct 15, 2024 · To understand how island arcs form, we first need to understand tectonic plates.

WebApr 19, 2024 · Island arcs are formed from the subduction and melting of oceanic crust as it descends into the mantle underneath a less dense oceanic crust at a convergent plate boundary. The subduction results in the creation of undersea volcanoes which then rise above sea level. The resulting volcanoes create a string of islands called an island arc. WebA volcanic arc (also known as a magmatic arc: 6.2 ) is a belt of volcanoes formed above a subducting oceanic tectonic plate, with the belt arranged in an arc shape as seen from above.
