Yes.
otseng wrote: ↑Thu Nov 18, 2021 7:39 amWould you agree there is practically no erosion compared to the final erosion while the layers were being deposited
No.
My assumption here is that you've been given the idea that the stratigraphy of the Grand Canyon area is much more uniform than it actually is, but again, what do you mean by "practically no erosion?"
otseng wrote: ↑Thu Nov 18, 2021 7:39 amAnd the effect of the erosion after millions of years for each unconformity is to perfectly form a parallel plane across a vast region?
This is another one of those "somewhere between literal and hyperbole" statements that I don't know exactly what you mean. Are you claiming that any of these unconformities lie atop formations that were eroded to exactly the same layer across some large area? The whole Grand Canyon? The entire Colorado Plateau? The world? What
exactly am I trying to show you?
otseng wrote: ↑Thu Nov 18, 2021 7:39 amWhy would this happen, esp when we see massive erosion after the layers were formed that definitely did not result in a flat landmass. Where do we see erosion causing a flat plane currently?
If I might make a request, knock off the rhetorical questions until we both understand
exactly what you're claiming.
What erosion of
what layers? What flat plane are you talking about, what is its extent, and why is it anomalous?
otseng wrote: ↑Thu Nov 18, 2021 7:39 amEven if erosion did happen to form a flat plane, where did all the sediments go?
Again, what flat plane and what are "all the sediments" that I am looking for? Depending on what you're asking for, the answer might be the
Colorado River delta, but I'm losing confidence in my ability to understand what you're asking.

The characteristics of several faults and their associated folds in the Grand Canyon district of Arizona are clearly shown by the excellent exposures of the rocks in the deeply dissected canyons of this region.
It would be good if can provide a photo so we can see what is being demonstrated.
You claimed that "folds or tectonic movement or earthquakes or any geologic activity" should be visible in the strata. Here is a scientist telling you that they are, which is a direct rebuttal to how I read your claim. If you intended more nuance than that, you didn't communicate it.
otseng wrote: ↑Thu Nov 18, 2021 7:39 amIf faults occur all the time while the layers were formed, we should expect to see a fault line stop at a stratum and a parallel layer deposited on top of that.
Is this what you mean?
This is a crop from a
larger image in a blog. That's a fault, then a tilt, then parallel layers deposited on top. Or do you mean something different?
otseng wrote: ↑Thu Nov 18, 2021 7:39 amIf each stratum represents millions of years, would it not be expected to see at least one fault in each layer? Esp since there's enough geologic activity in the area to have moved it up thousands of feet?
I'm trying not to get frustrated here, but not all geologic activity is the same. I already linked to at least one paper describing how the uplift was the result of the surface of the Earth being pushed up magma. It's measurable. That kind of uplift is far more gentle in a geologic sense, than say, the kind of subduction faulting in California that results in earthquakes. What kind of faulting are you expecting along with that? Or do you just think that there ought to be more faulting in general?
otseng wrote: ↑Thu Nov 18, 2021 7:39 amInstead, what we primarily see is a fault that goes through the entire strata.
In some places one sees that, but what do you mean by "primarily?" Can you write that in the form of, "if I am correct, there will be no examples of
X feature?"
otseng wrote: ↑Thu Nov 18, 2021 7:39 amAre those compatible with your idea of Grand Canyon geology? If so, do you still think that it's true that "faults or folds or tectonic movement or earthquakes or any geologic activity" aren't "recorded in every stratum?" If so, what specifically are you looking for, why do you think it's missing, and why do you think it shouldn't it be
Again, a visual would help so we can see what is being described.
Your earlier statement said that you wouldn't expect
any folding, tilting, or faulting, but later you linked a photo yourself that showed faulting. Clearly the earlier statement was hyperbolic, so what's my target? Tell me what kind of picture you'd like me to find. A lot of the time success just comes from knowing what geologists call a particular feature, but I also suspect that your ideas of both what the Grand Canyon is and should be are vague enough that you've thus far been able to dismiss disconfirming evidence as a series of mostly minor exceptions. My request is that you step back a moment to consider what you think are the defining features of the Canyon and list them for us with no hyperbole and without rhetorical questions. I suspect that many of your premises themselves are wrong in important ways, but stated in such a way that a geologist might agree with them because they're understanding the words differently than you are. I'm intimately familiar with creationist apologetics and even I'm having trouble figuring out exactly what you're asking.

I'm not so sure your calculations entirely apply. Your calculations would be for thermal energy, but not for kinetic energy. Yes, if the water was just sitting still and energy was applied to it, it would raise the temperature. But, during the rupture phase, the water was eroding rock and being thrust into the air. So, energy was being expended for these kinetic actions.
I think you're misunderstanding what "expended" means in this case. It's kind of nonintuitive, but if I drop a rock on the ground and it stops, the potential energy from holding the rock above the ground becomes kinetic energy as the rock falls. When the rock stops, the kinetic energy is transferred to the Earth, but doesn't disappear. In a frictionless universe, the kinetic energy would take the form of a wave that would travel through the medium forever, but friction converts what you're calling kinetic energy into heat (heat is technically kinetic energy for the purposes of energy conservation).
When the water shoots up, it erodes the rock by moving it. If the rocks are moving up (i.e. away from the center of gravity), then the kinetic energy is becoming potential energy. If they fall again, the potential energy once again becomes kinetic energy
without loss (conservation of energy). Energy "lost" to friction becomes what we're calling heat. When the rocks stop moving, either whatever stopped them or the mass of the rocks themselves gains the energy. Friction ultimately converts the energy (again
losslessly) into heat. When we talk about energy loss, that loss is the conversion to heat.
If there is enough potential energy stored in the rock layer atop the subterranean reservoirs to shoot the water up in the air, that energy ends up as heat if that water comes to rest at any point below its maximum height. As I said before, this is counterintuitive because things like the surface of the Earth, the atmosphere, and the oceans are immensely massive heat sinks compare to even the largest rock we might drop. You're talking, though, about the ocean itself, or some huge fraction of it, replacing the dropped rock. If a thousand kilograms of water is shot 430 meters in the air and returns to the surface, that energy will impart enough heat to have raised that thousand kilograms one degree celsius. Some of it might go into the air, some into the rock, and some into a larger pool of water, but the energy never disappears. Ultimately, it would be radiated away into space, but that takes time and without divine intervention, it's longer than Noah has.

Are you suggesting there are other places where the pattern does not exist? If so, please provide such examples.
I'm assuming again that your understanding of that question is somehow nonliteral, but maybe it's not. I went to Michigan Technological University in Michigan's Upper Peninsula and spent a lot of time in the Huron mountains. The land surface there (and much of the shore of Lake Superior) is made up of metamorphic rock dating to the precambrian, so it completely lacks the sedimentary layers of the Grand Canyon and therefore lacks the pattern.
Does that answer your question or do you mean something different by it?

and for the entire area to remain level without any signs of tilting?
Accorging to
current theory, the entire Colorado Plateau curved due to magma forces over a such a large area that it's measurable in terms of elevation differences, but not apparent to an observer on the ground. It sank around the edges and rose in the middle.
otseng wrote: ↑Thu Nov 18, 2021 7:39 amObservation evidence does not show a dome pushing up. I've already posted many images of the Grand Canyon at scale that show parallel layers over the entire region with no central bulge. But, if necessary I can post more.
I went back and reread what you wrote and my confusion was your vague "entire region." I took "entire region" to mean the entire Colorado Plateau. Since you claim to be looking for evidence in photographs, you obviously meant something much smaller and more local.
Regardless, the mechanism in that paper explains what you're seeing. The Grand Canyon area was lifted with very little deformation by magma beneath the crust. So, to try again to narrow down exactly what question I'm answering, do you think that the Grand Canyon wasn't uplifted at all? Was it uplifted by some Flood mechanism that no other natural mechanism can account for?
So far, this argument looks like "that's flat and I don't think it should be." I pointed you to a paper that says, "that's flat and here's one way that could have happened." That doesn't have to be the answer that you're looking for, but I'd prefer to stop having to guess at what you
are looking for.
otseng wrote: ↑Thu Nov 18, 2021 7:39 amEven if magma from below was able to push the entire region straight up, the Grand Canyon is just the start of the problems. This would have to be explained for every canyon in the world. So, underlying each canyon is a "vertical high-seismic-velocity anomaly" that is able to uplift each canyon perfectly straight up?
Hopefully not all at once, because that's what starts a Gish gallop. After you agree (if you ever do) that there's a plausible mechanism for the Grand Canyon, we should first check to make sure that the next canyon shares details with the Grand Canyon that you think it does. I'm getting the impression that we're all assuming that our understandings of even modern details about the Grand Canyon are shared and they're not. I'd like to see a list of premises as detailed and literal as possible, but that might not be practical. Instead, when you refine an old question or ask a new one, please write it in such a way that it can be understood literally and without assumptions.
