Briefly explain why the oceanic ridges are higher than the surrounding ocean basins?

What will be an ideal response?


The oceanic ridges are hot because they have not cooled entirely from their formation from magma at the plate boundary. In general, hot material is less dense than cold material and so the hot parts of the lithosphere are more buoyant than the cooler parts causing them to rise.
