So I'm listening to the interview. And it seems that Niel is saying that long ago, when the planet formed, lighter density rocks floated to the surface.
Which, of course, is true. But this means that there would be an essentially even distribution of granitic rock across the surface of the earth. The earth certainly does not have that today, with mountainous regions having a crust at least twice as thick as that of continental crust on average (itself thicker on average than oceanic crust). Now why would that be? How could that happen? Oh, gee, I don't know, maybe collision? Since granitic rock doesn't really subduct, it crumples and a divergent zone is produced elsewhere. This produces oceanic crust. What's so difficult about that? Granted, I have quite the simple model, but still.

Back in the late 70s I took a little 1 unit class called geology field trip and one of the exhibits was a set of bleachers in Hollister built directly on the San Andreas fault (the actual boundary between the Pacific and North American Plates) in the late 50s. Well by the late 70s, the bleachers had moved about 18 inches along a diagonal right on through the whole setup, displacing the bench seats. Now conceivably if one set up a very slow motion camera, say a frame every few days to a week, and one made sure the camera itself did not move in the rather frequent earthquakes, one would be able to directly observe the bleachers being moved on the film when speeded up to the usual 32 frames per second, or thereabouts. Just a thought. Seems to me that plate movement can be observed, just not on the regular human timescale. It would be like those movies of buildings or bridges being erected, to deny the movement between the plates would be the equivalent of denying the building or bridge exists.

Exactly. You could also mention the physical scale. Subduction in particular doesn't happen at a location that could be "filmed". It happens over massive distances and at quite some depth. Also, if I can recall correctly, on top of the subduction boundary will be a pileup of material that essentially gets scraped off the top of the plate as it gets subducted called an accretionary wedge (forgive my spelling). So even if you wanted to "watch" the subduction it is in fact buried beneath a vast amount of tons of ... well ... stuff. Again IIRC, Indonesia itself is an accretionary wedge so these things can be quite big. I think plate tectonics is on topic in the sense that it is the reason for the mountain building, so I guess demonstrating that it does happen by talking about subduction is okay, but we may be slightly stepping into different territory. The take home point is, crazy Batman guy aside, plate tectonics does happen AND is sufficient to account for mountain building. That is a fact that needs to be accomodated by any model claiming to accuratly describe the history of the earth. Even if someone wants to argue about forces and equations and such, which seems pretty easy to debunk, although I am not sure it has been done yet comprehensivly enough, which I will leave to the physics minded folks; mountains building regions correspond directly with convergent plate boundaries. Either that is a coincidence or someone's math is wrong. Edited by Jazzns, : No reason given.

Actually Jazz, I recall watching a video back in school where some organization took a robot sub down, left it therefore a month and had a time lapse showing the tiny movement between the two plates in the Mid Atlantic ridge. But that was a long time ago.

I think the plate tectonics discussion looks pretty good. It, however, is pretty marginal to this topic and would be better served by a specific to plate tectonics topic. Hint: Someone propose such - Put a quality topic title on it and link back to a good place in this topic.
This topic seems to have long ago run its on-topic course. Closing it down. If someone has some fossils on mountains point they wish to pursue further, it's also new topic time. Closing this one down in about 15 minutes. Adminnemooseus

The mid-atlantic ridge is a divergent plate boundary. No subduction occurs there.
If you want to see subduction, I recommend looking at the Juan de Fuca plate. It is currently being subducted underneath the Cascades and should eventually vanish if plate tectonics is right. Of course, we'll have to wait a very long time for it to completely vanish, but in the meantime it should be possible to measure how much it is shrinking. And yeah, video of it happening isn't exactly possible. [abe: adminmoose was putting up his warning as I posted this. sorry about that.] Edited by kuresu, : No reason given.

From ICANT on Age Correlations and An Old Earth, Version 2 No 1
For every spot of earth that is known to be covered by floods there were other spots that were not. All known floods were local/regional floods. There are also land that was originally seabed that has been lifted up above sea level (Mt Everest for example), and they have evidence of mature marine ecosystem growth in several layers, and the periods of those growth exceed thousands of years. I would expect to see evidence of flooding all occurring at the same time ... ie universal in the spacial-temporal matrix in the same way the evidence of a meteor impact in the Yucatan left a layer of Iridium around the world as dust from the impact settle world wide (demonstrating how massive the impact was). I would also expect to see a mass extinction event, as was seen from this impact causing a "nuclear winter" alteration that affected most living creatures, but with all deaths associated with flooding. See Wiki Chicxulub Crater, Mass Extinction quote: I would NOT expect to see evidence of marine growth in the muck from such a flood, as it would not have had sufficient time to develop the mature ecology seen in shell deposits. This is discussed in detail at the beginning of this thread.

Unfortunately no reference was cited for this (mis)information. quote: So it looks like the Himalayas began to be trust up 50 million years ago. The shells would be somewhat older.

Meaning thousands of years to build up the layers and layers showing growth within a mature marine ecology. quote: Qomolangma is the Tibetan name for Mt. Everest. ... "trilobites, brachiopods, ostracods and crinoids" ... many of which are now extinct. Brachiopods are interesting critters, the larvae are free swimming before settling to the bottom and attaching themselves to the substrate with a pedicle. They also have growth lines, and live from 3 to 30 years. Lower down the mountain is a different kind of rock, not metamorphic but sedimentary, and the shells there are complete: quote: Perhaps some creationist can explain how you can have one layer of mature marine growth on top of another one without the water existing there for decades, if not millennia, and then add up all the layers that make up the limestone formation and other rocks to depths of 200 meters or more, adding decades (or more) for each layer ... Let the song and dance, complete with hand-waving and wails of denial commence. Because it is always the details that flummox creationist facile "explanations" based on ignorance of the total evidence.

What? I read through your OP and some of the responses to it and don't get how any of this is a problem for the Flood. What you are interpreting as "mature marine growth" means what? A bunch of marine fossils collected together in a rock, isn't that all it is? "Without the water existing there" means what? The marine fossils in rock layers at the tops of mountains suggest deposition by the Flood before those mountains existed. Then tectonic pressure pushed them up all over the earth so that all those fossils are embedded there in the rocks at the tops of the mountains.
Where are you getting this "decades" stuff? This is just the usual situation of the deposition of limestone layers containing dead marine creatures one after another in the Flood.
Uh huh. Well, have at it.

There's also some idea that the more deeply embedded the fossils are the longer the Flood should have taken. Why? If the argument is that the Flood simply covered existing mountains, that could explain the fossils ON the mountaintops, yes, but the idea is that the Flood deposited all the sedimentary layers that contain fossils, and in the case of mountains this would have happened before the mountains had been raised. After the Flood, the fossil-containing strata were pushed up to become mountains, which is why the fossils are IN the mountain and not just on it.

A couple of things if I can interject. Mainly, it means that the bottom of the sea had time to go from a featureless, unpopulated surface to a community of organisms. In other words it became an ecosystem. Considering the growth layers in brachiopod shells or the slow development of coral reefs and other such features, this takes a certain amount of time, certainly exceeding year. But even more importantly, how do you get a layered sequence of such communities one after another in the geological record if it is caused by a one-year flood?
No, it is a lot more than that. It is information that tells us something about the past.
Or deposition by normal marine sedimentation before mountain building.

For the same reason that it took longer to build the Notre Dame than it did a back yard shed. You don't get hundreds of feet of coral growth in a single year.
What evidence do you have for rapid mountain building?
