Water gets a little large as it freezes, but that behavior is rare among
solids.

I have difficulty with the plate tectonics for
two main reasons. The first is that tectonics
appears to be an incomplete view.

Seems complete enough for me. What's missing?

All self
organized systems are comprised of two
basic processes.

What's a self-organized system? How do you know it has *two* basic
processes?

One would be a static process

What's a static process? Static means not moving.

of simple, predictable change such as sea
floor spreading. Combined with it's opposite chaotic
attractor such as periodic catastrophic change.
Plate tectonics appears to explain only the static
attractor behavior, and thus seems incomplete.

Oh, you mean like earthquakes and volcanoes?

I envision an evolutionary process where the crust
hardens completely, the internal heat steadily builds up
until a sudden catastrophic period of expansion occurs.
And over again. Much like is thought to happen
on Venus.

You can envision it, but there needs to be evidence and some geophysical
calculations that show that this could be happening.

The second reason I have trouble with plate tectonics
is the notion the earth's diameter would remain
relatively unchanged throughout the course of
solar system evolution.

Nothing inherently wrong with that.

We live in a universe where
nothing at all remains unchanging.

That's too fluffy to draw any conclusions from.

Even the
universal constants evolve over time.

Perhaps, but in very small amounts; not nearly enough to demand a change
in the Earth's size.

Plate tectonics
as it is now seems counter intuitive.

Lots of theories are counterintuitive. That's usually a sign that you
don't fully understand them.
