Contrarily to what affirms Aidan, the Earth Expansion does not

By the way, don't you think that present quote from some of you, the

http://www.hi.is/~oi/svalbard_geology.htm
Outline of the Physical Geography and Geology of Svalbard
Ólafur Ingólfsson
GEOLOGY
Svalbard has a very rich, diverse and long geologic history that makes
it somewhat of a 'mecca' for geologists; a place where a great
variety of geology can be studied and where much can be learned about
the development of tectonic features and sedimentary environments
through time as well as the drift of continents across the Earths
surface. The oldest till deposits on Svalbard were probably deposited
when Spitsbergen was situated close to the South Pole, some 600
million years (MY) ago, and the red Devonian sandstone of northern
Spitsbergen was deposited when Svalbard was close to the Equator, some
350-400 MY ago.
ENDQUOTE
... and all those continents go on a merry go round .... transporting
on their back their mountains ranges & crossing sea trenches & mid-
ocean ridges on the way ...
Hey idiotic Continental Rafters ? What is the depth of those
Continental keels ... any idea ?

you're right. I just did dome figgering. Even if 100 tonnes fell per day, in one
million years, that's less than one thousandth of one billionth (English, not
US) of the earth's mass.
piddling small, isn't it. |

Using a nice round number of 10 tonnes/day
= 10,000 kg / day (just to keep everything in proper units).
= 3,652,800 kg/year (just over 365 and a quarter days/year, varies slightly
over the next period)
= 730,560,000,000,000 kg over the last 200 million years (one of the EE people
has a thing about his claimed expansion starting in the Triassic ; again, just a round
number)
= 292,224,000,000 m^3 at 2500kg/m^3
This volume would account for a spherical shell on the surface of the Earth
which is ... I make it 0.00057m thick. Unless I've slipped a digit somewhere.
Quick check, a 1m thick shell on the nominal Earth diameter will have a volume
of 510,064,551,970,139 m^3. Yes, around 200 times more than meteoric accretion. I have
a feeling I got a figure of about a half-mm the last time I did this calculation.

Heh. When dealing with "nice round numbers", you are encouraged to round
off the final results. For this calculation, even rounding off the
intermediate results is allowed. For instance, "730,560,000,000,000 kg"
is best expressed as 10^15 kg. :-)

Wow ! look at all the weight for 1 metre
Imagine moving 100.000's times more weight than that by a mechanism
of thermal convection.
Now that you have your calculator out, how much heat do you need to
rise 1 metre of composition up 1 metre and then apply it to the
internal dynamics
I am sorry that I will not be around for the answer,plate tectonics
remains a great idea but is lost to 'convection cell' advocates.and
there is nobody around to deal with the matter,not by yelling for
rotational dynamics but acknowledging that the thermally driven cells
are just too absurd and counter-productive.
Doubt it will happen though,too many dull people like yourself around. |

WHY is the mantle homogeneous ? If convection didn't exist would you
not expect heavy elements to collect at the base of the mantle?
Because the mantle is in continuous motion ( tranmitting internal heat
to the surface ) the mineralology is everywhere the same . Plate
Tectonics is just a minor consequence. And, why do you call it
geostationary ? |

There you go again, whining about some distantly related topic that has
nothing to do with the actual question at hand, namely how the Earth's
rotation is supposed to move the continents. You've *never* answered
that question in any meaningful way.
Quote: I do think a person suffers from a genuine illness if they cannot
interpret actual images of the Earth overtaking the planets as the
only way to affirm our and their motion around the central Sun but
even here it appears that the illness is far more entrenched than I
could have imagined,a real human illness that cannot find fault with
the false view of Newton that completely destroys the main Western
astronomical achievement of Copernicus known to Kepler and Galileo .
There you go again, avoiding the real question by whining about Newton
some more, as though I hadn't just told you that you sound like a kook
when you do that. Must be a side effect of your intelligence.
Quote: It is refreshing seeing somebody so open about convection cells and
good for you,keep up the good work in cleaning up grammar and notation
you hear and don't mind me and my idea of this rotating Earth thing.It
is already taking on a life of its own so I expect you to defend a
stationary Earth with all the intelligence you display with me.
I'm not defending a stationary Earth. You're just making that up because
you don't understand what I wrote and you desperately need to distract
the discussion from the real question.
You're a kook. (Well, even if you're not an actual kook, you meet enough
of the requirements that, until presented with strong evidence to the
contrary, I will provisionally consider you a kook.)

WHY is the mantle homogeneous ? If convection didn't exist would you
not expect heavy elements to collect at the base of the mantle?
Because the mantle is in continuous motion ( tranmitting internal heat
to the surface ) the mineralology is everywhere the same . Plate
Tectonics is just a minor consequence. And, why do you call it
geostationary ?
It was originally Oriel's shorthand for the notion that Earth's
revolution does not affect mantle convection: In all models of mantle
convection, the earth's rotation is ignored. He mysteriously graduated
from that to claiming that geologists say the Earth does not rotate.

WHY is the mantle homogeneous ?
Take the widest view possible -
The Earth is rotating
The shape of the Earth is not a perfect sphere
The fractured crust sits atop a rotating molten/flexible composition
and profile this imperfect sphere.
------------------------------------------------------------------------------------------------------------------------------------------------------------
Narrow the view slightly -
How does rotation condition a 40 km deviation from a perfect sphere
Where are there exmples of this elsewhere in rotating objects with an
exposed flexible state
--------------------------------------------------------------------------------------------------------------------------------------------------
Shift gears and take a look at stellar dynamics -
For a given star of roughly the same size and composition,there is a
correlation between maximum equatorial speed,differential rotation
rates and deviation from a pshere.
Any change in composition,rotational speed will affect the
differential rotation rates and subsequently the shape of the star.
------------------------------------------------------------------------------------------------------------------------------------------------------------------
Return to the rotation of the flexible/molten interior of the Earth -
What exempts the Earth from the same generalised rotational dynamics
which correlate maximum equatorial speed,interior composition and
spherical deviation.The missing component is differential rotation.
What alternative rotational mechanism can be proposed to differential
rotation of the interior composition to generate the spherical
deviation
------------------------------------------------------------------------------------------------------------------------------------------------------------
Considering that generalised dynamics do not prohibit differential
rotation in the Earth's interior,it stands to reason that it is a
satisfactory means to explain the 40 km deviation without knowing what
the internal composition and viscosity is.In allowing lattitudinal
shear bands which occur where differential rotation occurs in stellar
dynamics,the differential rates automatically qualify as the mechanism
for crustal motion.It may just be possible to see the slightly
different rotation rates from actual images of the rotating stellar
composition but that is the nub of the agument for a rotational
mechanism -

Quote: not expect heavy elements to collect at the base of the mantle?
Differential rotation is not a conclusion,it is a point of departure
along with maximum equatorial speed, and spherical deviation for
determining what the composition and viscosity of the interior is.If
you begin with internal composition,viscosity organised around a
geostationary thermally driven convection cells you will get a
different set of criteria as opposed to a rotational mechanism and
that is the central argument.

There would always come a time when the internal mechanism would begin
to overshadow the outlines of plate tectonics and reduce it to a
'minor consequence' as you would put it in an effort to promote a
geostationary convection cell notion.You csn hide a lot of junk
behind convection cells mainly because they can only be speculated
while rotational dynamics and specifically differential rotation has a
sequential logic to it and can be derived from observing the behavior
of other rotating celestial objects.
Your convection cells notion are geostationary insofar as not only do
they require no reference to axial rotation and planetary shape,they
prohibit differential rotation as a mechanism which binds plametary
shape with crustal motion,For differential rotation to
exist,convection cells have to go and that is about as straight an
answer as I can give.
The geological material is a joy to work with and I never stop
reminding participants that it is not really that important to
establish an internal mechanism,only if it is done,to make sure that
it has the best possible chance of explaining multiple features and
effects rather than a means to an end,something which the ad hoc
ceonvection cell solution would have served.I cannot repeat it often
enough,I am absolutely astonished that the entire community is
prepared to let an observed orbital component to drift by maintaining
variable axial inclination,whatever chance the rotational dynamics
have of emerging,it cannot happen without first handling the observed
motions of the Earth.
It is always easy to point out wrong approaches just for the sake of
it however it is far more difficult to promote a more productive view
of things thereby setting aside older and less productive concepts. |
