So, .. colliding plates, driven by subducting slabs, are pushing the crust up (but not crumpling it)? And only slabs around the Pacific (because the geology of continental margins tells us there are, and never have been, any others). I mean, who are these Plate Tectonics people kidding? This old cold, grandfather of a slab, with no energy left (which is why he's sinking back into the mantle), is pushing up the Earth's crust as he goes, .. not just around the draw-cord of the body-bag, but further afield as well. Gee, .. what a restless old git. One last hurrah, eh? Not for him the going quietly.
Well, .. good on him, .. but it's tripe. Hardly even half-cooked at that. Pushing up daisies, maybe, .. but mountains? I don't think so.
Now, .. if they said that the crust all around that draw-cord was getting pulled down with him and collapsing, .. that would be more credible - because it actually is, .. but PTeros play this down and advertise it as a zone of pushing up.
But it still wouldn't account for the the collapsing further afield, would it? Trace that surface all over Turkey and (in the language of Plate tectonics) it is rising due to the collision of the African Plate with the Eurasian one, and ask yourself if it is likely that those massive 'plates' are moving because subducting slabs of oceanic crust around the Pacific are pulling (or pushing) other pieces of crust around (as they fall, spent, .. back into the mantle). Because that's what they say. This would be a good exercise for schoolchildren before playtime, using Google Earth - to see how far the Anatolian Plateau can be traced, and see if it's politically correct and stops at the country's border.
Much more sensible to rationalise that it is not that bit of the land on the left that is rising, but the other bit of it on the right that is falling.
But how? There is nowhere for it to fall to, is there? The Earth isn't hollow, .. surely? There aren't big holes down there, lurking for unsuspecting lumps of crust to fall into, .. so how come there is such a thing as subsidence? Well, then we have to use our heads instead of reading what we're told, and instead of saying all that guff about subduction half a world away, say, .."Why isn't it just that the Earth's crust is being pulled apart, right there, .. sideways, making all those faults and rifts that we can map. It's not an ad-hoc postulate at all. We really can map them. They're real. Pull-aparts, .. faults,
.. rifts, .. some of them full of basinal sediments thousands of metres thick, .. and not just pull-aparts on the continental crust, but on the ocean floors as well. In fact the ocean floors are riddled with faults; it's virtually what ocean floors are - graveyards of grandfathered faults. They make up the biggest landform of the planet ( as abyssal hills)! Both of them, continents and ocean floors, .. full of rifts.
And then, starting with the *FACT* of continental extension (and the many rifts and faults in it of the sort above), how do we rationalise the necessary increase in space on the surface of a constant-sized Earth that lets that fact exist?
The answer is we can't (on a constant-sized Earth). There needs to be an increase in surface area for the pre-existing crust to collapse, or the crust is forever supported by the mantle underneath. "Increase in surface area"? Did somebody say something about "sea-floor spreading"? ("Deserving of a noble prize"?) (So it is/was. But they rather screwed it up with the stupid posutlate of subduction that denies the evidence and the logic apparent of everything geological we see.) ( Too bad. Long story, and an interesting one - as an illustration of the core values of science. We're pretty lucky we get the spin-off we do, when all's said and done - and paid for.)
The continental crust is full of faults, pull-aparts, and sedimentary accumulations in them, .. and hills. Even mountains, .. left behind as the tardy participants in this collapsing behaviour . Switch on the Panoramio in Google Earth, and see the mountains that Turkey is riddled with, .. mountains that are the tracts of land that can't keep up with the erosion that's doing its level best to make them (level). Where's the logic in saying (as Plate Tectonics does), that these mountains are due to subducting slabs, the last hurrah before grandfathered slabs cark it, even as the strings on the body bag are drawn tight and they get shoved down into the mantle ? I mean, .. fair go! Gravity got the Earth together in the first place. Made it big, made it round. And differentiated it into a core, mantle and a crust. And put the radioactivity (heat) where it belongs. And now that heat is supposedly going to set up convection cells, which are going to do their level best to break everything up everywhere, .. and as a by-product of returning to the mantle when they have lost all their energy, do their level best to build mountains. Well at least it can be said that the best is a level one. It's about they only thing these 'convectioneers' have right.
Some trick! And there is a worldful of people calling themselves clever and asking for research money to work out how this can actually be done, while you and me can take just one look at that picture and say, "Bullshit", the land is clearly falling, .. the high ground on the left just happens to be falling more slowly than that on the right. And save everybody a lot of time and trouble (and money) into the bargain.
(Recap: the land is not rising by Plate Tectonics, because colliding plates and crustal crumpling is not a mechanism for forming plateau and near-plateau surfaces that were once the legacy of land getting eroded down to zilch - or even made up the sea floor, and that can now be extensively correlated around the world in the singular elevation of the circumglobal mountain belt, which the global geological picture tells us is the ancient Pangaean equatorial zone)
"So what's causing the land to fall?"
"The surface getting spread. The collapse is just it taking up the room that's becoming available."
"And why is the surface spreading?"
"Because the Earth's surface is moving out from the centre, .. it's getting bigger. Well, it's *got* bigger - by the extents of the ocean floors. The Mediterranean, .. if you do a local check. And the Caspian and Black Seas as well - incipient Mediterraneans, ..'Med-extensions', if you like."
"And why is it getting bigger? That's a hell of an amount (the ocean floors)."
"Sure is. Considered as a volume it's doubled the size of the Earth from where it used to be not so long ago. Guess you could say it's exploding."
"Wow!"
"Yeah, .. wow.. Ennyhow, it's not going to happen any time soon."
(?? But it *is* happening now. Earthquakes are happening all the time. They're going off faster than a lazer, .. geologically speaking. *That* (and tsunamis) is our experience of the energy release of 'exploding' as we experience it today - curvature correction by crustal collapse in response to mantle breakthrough as the Earth gets bigger.)
