How do ocean ridges form
WebSep 26, 2024 · The oceanic ridge system is an underground mountain range formation on the sea floor. Discover the tectonic activity that led to the formation of the oceanic ridge system, and explore the... 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.
