Seafloor spreading is a process that occurs at mid-ocean ridges. The process of sea floor spreading occurs when oceanic crust forms via volcanic activity.
Seafloor spreading starts as a split as a continental land mass. The process starts with temperatures rising at the base of the continental crust. This then causes the crust to become more plastic and less compacted. As the crust goes up, tiny breaks occur. They then over a long period of time, grow into rifts, usually at around 120 degree angles.These sections are called triple junctions. Since the new oceanic basins are shallower than the old oceanic basins, the total capacity of the world's ocean basins decreases when the active sea floor spreads.
