Mar 19, 2009 · When two oceanic plates move apart, the magma rise through the gap, to the floor and solidify, thus forming new crust and adding on to the ocean floor, allowing the seafloor to spread. Mid-oceanic ridges and deep sea trenches are also formed in the process.

Hot mantle from the two adjacent cells rises at the ridge axis, creating new ocean crust. The top limb of the convection cell moves horizontally away from the ridge crest, as does the new seafloor. The outer limbs of the convection cells plunge down into the deeper mantle, dragging oceanic crust as well. This takes place at the deep sea trenches.
