Debunking Plate Tectonics - Strike 2.

So, ..on the simple grounds that the popular models of soup and
porridge promulgated to support Plate Tectonics
------------------------------------
"The mobile rock beneath the rigid plates is believed to be moving in a
circular manner somewhat like a pot of thick soup when heated to
boiling. The heated soup rises to the surface, spreads and begins to
cool, and then sinks back to the bottom of the pot where it is reheated
and rises again."

...... is pure nonsense, I am claiming a second strike.

There is no reason why the solid rock of the mantle should be more
representative of soup and porridge than it is of tea. In fact, since
we get irregular motion of the tea -leaves rising when the pot is
heated, there would seem to be a closer analogue with the irregular
'convection' that is actually supposed to happen in the mantle. The
standard model of convection

is no longer considered relevant.

"Although the concept of plate tectonics is universally accepted, it is
incomplete in that there is no agreement on the mechanism that drives
the plates. It has been suggested that they are driven from the side,
that is pulled by subducting slabs and pushed by negative buoyancy
forces from subsidence of oceanic plates ("ridge-push" force). Another
view is that plate motion is driven by mantle convection. The motion of
the plates can be explained by either of these concepts."

"Incomplete"? - Read 'irrelevant'. It's based on nonsense..
(You'll even get conflicting opinions whether the heat source is
supposed to be in the mantle or in the core.)

You can try (with difficulty) to argue one or the other (plate
mechanisms or core mantle mechanisms) , ...But not both of either case.
Quadrupling models for what drives plate tectonics quarters its
validity, not multiplies it. But it's not 'quadrupling', ..is it?
It's 1/ 4x3x2, which makes it 1/24th. And that's just with those
bloopers. You can see it's rapidly approaching bull****, ..and that's
just with the theery, ..we haven't even begun with the GEOLORGIE.

But don't worry, .. it's only exam after all. And you're all a dead
cert to fail. So why don't y'all just head off down to the pub and
indulge in some pre-apocalyse commiseration. Marc there doesn't even
want you to talk about it (the distribution of origins of Life on
Earth) ...you're only making him feel nervous.

Where's the Woof? I know, ...(swotting hard.)

(Now, what have we got? Just 11, ..is that all? )
