Four-panel diagram showing the geological process of back-arc basin formation above a subducting oceanic plate. Each panel illustrates stages in which melted rock rises above the subducting plate, forming an arc, back-arc rift, spreading center, and eventually a back-arc basin, with labeled features including ocean, crust, trench, asthenosphere, and new volcanic arcs.
