Ridge push and rifting
WebRidge push is largely from positive buoyancy, i.e. new oceanic lithosphere is created at mid-ocean ridges and this lithosphere is very warm and less dense than the lithosphere adjacent to it (away from the ridge) and so is sitting higher than the adjacent lithosphere, this translates to some force pushing away from the ridge.
