How does a ocean ridge form
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. WebA sandbar at a beach is a sand ridge that forms over time off the coast. The current pushing from the coast meets the current pushing toward the coast, resulting in sand gathering in …
