Are you kidding? ketchup is NOT a Bingham plastic! It is not solid
neither under stress.

then why doesn't it just pour out of the ketchup bottle? (Heinz that
is)

There are plenty of other examples. Toothpaste

Try one.

Consult the food science/technology literature.



"ketchup science" is really all you can do?

It is how science work, at least in my field which is not fucked up like
geophysics.

You don't have a field.

I do. You would know it you knew how to use google scholar. But I don't
expect to much from you, nor from Georgie or the like. Vous �tes des
mauvais (I let you find the translation that should be easy for a smart
ass).


You're no science scholar period.



And don't get sore at me because Geophysics has a large literature
regarding
both experimental and theoretical studies of creep in crystalline
rocks

Whatever. The studies of creep are never done under the condition of
THERMAL CONVECTION.

Irrelevant.


A stress is sufficient for creep, no need for heat transfer,

I never claimed anything else silly goose

However, thermal buoyancy can generate the necessary stress.
As you understand above, that is all that is necessary.



and this is
exactly what happens during planetary growth.


there has been no such thing as planetary growth since 4.5 billion
years ago.

If so, you'll need to explain why the Earth's complement Pb, U
ratios falls on the meteorite isochron.

Oops.. yet more special pleading for you.



The excess of material
produced "somewhere"

That would be fantasy land.


in the planet is pushing material toward the
surface (diapirism, plume) and it turns into volcanism, uplift and

*turns it into* ? Why should material be pushed to the surface in
the
form of plumes? Why not a gentle swelling of the planet?


nappes.

while EE has no theory, no experiments, and to boot no unambiguous
measurements of expansion of the Earth or its moon for that matter.

More ducking:

Plate tectonics is a bad model that can't explain patterns of ocean
floor like this one:

Oh, by the way Stuart, for your information, ketchup in a pot does not
convect. It is the water contained in ketchup that vaporizes and makes
bubbles. There is phase separation in the process.

Is that right. Well, there's a big difference between something
behaving LIKE a fluid and it BEING one. Solid rock, despite it
deforming into more contortions than an Indian/ Egyptial/ Balinese
Belly Dancer, is not a fluid. Crystal gliding and accompanying
recrystallisation and movement on faults/ microfaults (and the
language to conveniently describe it) is NOT *fluid* flow. You're
only fooling yourself if you think you can apply the same equations of
state. What's more, all of that stuff, all those contortions that
makes you think lovingly of belly dancing, is *stress* induced, more
than it is temperature induced.

In this case of continental rocks, I would tend to agree.

Good.


Simple point is, under stress rock will flow, yes?



No. Not until you answer the bit about the mantle slab getting
"forced down"

You mean pulled down?

No, ..I mean what they say:- "forced down"
http://users.indigo.net.au/don/nonsense/fails.html
Where do they get the idea of 'forcing down'

I didn't say boil it. Put a cold bath on top.

You're welcome to try it yourself Stuart. I invite you to look in
detailst to what happen in your pot.

Clue: Ketchup can be described as dense solid particles in suspension in
water.

No kidding. And suspensions often have nonlinear rheologies.

Jeez, is that an euphemism?

There are at least two phases in your ketchup, a liquid one and a solid
one. You might use ketchup as an analogy to a melt, but hardly for
peridotite!

The analogy is with the nonlinear rheology, not the compositional
makeup.

Hu? If I understand correctly, you claim that the nonlinear rheology of
a multiphase material like ketchup would be analogous to the non linear
rheology of peridotite???

Don't understand what your problem is.

Suppose I have two fluids, both with rheologies characterized by
a power law index of 5 for example, what difference does it make
if one is peridotite or the other is ketchup?

Ketchup is multiphase material (solid+liquid), peridotite is not. the
analogy is bogus.

Doesn't matter if they both behave the same way when stressed.

The analogy is bogus because in a multiphase material like ketchup, heat
transfer will be different than in an solid.
