Mercurio I don't have time at present to refute each of your points. The basic issue is that plate tectonics is powered by mantle convection currents. Any other effects are secondary. Those two points woould be accepted by 99.8% of geologists. If you are proposing something else it requires evidence. You keep presenting consequences as if they were causes. Example: in your last post you say "You asked where the energy comes from when globs get sucked under, added or just gas. Artists impression from the Cambridge would say gaseous:" No those are not bubbles of gas, those are magma melts. Where did the energy come from to melt them? The heat of the mantle. Once again they are a consequence not a cause.
