Answer 2

Answer:

The melting of subducting oceanic crust located in a subduction zone is the “key ingredient” to the creation of new oceanic ridges.

Basically the ocean ridge is an underwater mountain that formed by plates tectonics, and such plates can uplift the oceanic floor or level when convection currents rise in the mantle beneath the oceanic crust. As results, magma are created where two tectonic plates meet at a divergent boundary.
