WebSep 27, 2024 · At both mid-ocean ridges and back-arc basins, the molten magma of Earth's asthenosphere wells up close to the surface. Mid-ocean ridges form at divergent plate boundaries, where tectonic plates are moving apart from each other. New oceanic crust is formed at mid-ocean ridges.
WebWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. how to return digital game amazonWebMountain building.
