Description

The genesis of an ocean: in plate tectonics, the formation of an ocean starts with a rifting process in the crust as a result of mantle convection. A valley forms like the African Rift Valley beeing a recent example. In the next stage, the valley has opened up until sea water enters; a good example is the Red Sea. The spreading process continues, the ocean becomes wider and forms a mature ocean like the Atlantic.
