The magnetic stripes that accompany many of the ocean ridges can be explained by a thin plate thrust out over the former sea floor. The force moving the plate is suggested to be created by a wide upward pointing wedge of solidified basalt moved upward by a 60 km deep column of hot, and therefore light, lava and plastic rock. That hydraulic pressure is translated into lateral pressure by the wedge. Periodically the wedge fails at the centerline and, upon sinking into the magma near the surface, is widened. Thus it is renewed for the next cycle when the magma which flows into the opened faults freezes.
