As we have stated, the Atlantic will widen and the Pacific will shorten. Where the Pacific effect will cause sudden and violent subduction of several plates, which are already subducting, in the Atlantic the effect will be the opposite. A gulf will appear, with plates torn apart and the softer magma under the plates exposed to the cold Atlantic water. Where this will harden the magma, and establish new plate surface, there will be less support for the abridging plates, those that attach however remotely to the shorelines of the Americas, Europe, and Africa. These non-supported plates will sink, somewhat, bringing their formerly above-water land masses down under the water in many places. As an instance, Europe and in particular the western islands of Britain and Ireland will find itself more affected than some other parts of the globe.
