Center sea edges are the limit that happen between structural plates and they are where the plates move far from one another. At the edges of the edges, magma from the underneath mantle ejects, cools and wind up hardened, along these lines framing new sea covering.
New crust forms AT OCEAN RIDGES. The correct option is D. Middle ocean ridges are the boundary that occur between tectonic plates and they are the locations where the plates move away from each other. At the edges of the ridges, magma from the underneath mantle erupts, cools and become solidified, thus forming new ocean crust.
