Here are a few thoughts about each of the four possibilities. There's a non-existent link at the moment; I've got the pictures but not the time to put the page together.stipe said:I think it's all hydroplate (possibly covered in secondary basalt flows) except right around where the rift blew through.
Okay, a draft of that link is now on line. And I do want to reiterate that I'm fully aware that just because I haven't found the answers in that mess of an on-line book doesn't mean they're not in there somewhere!aharvey said:Here are a few thoughts about each of the four possibilities.

I think you've left parts out of your model. Your problems would be an issue if the rift had formed immediately and simultaneously all round the Earth, but the hypothesis demands that one point fails first. That point will generate the greatest pressures and erosion rates. The areas away from it will donate material and energy toward that point.aharvey said:Now, you'll notice I haven't illustrated step 5. That's because I don't see how to do so! Because the rift completely encircles the globe, both pieces of the hydroplate are completely encircled by the rift and its resulting Ridge. If a piece of hydroplate is being pushed from all sides by a rising ridge, then how far, and in which direction, can it actually slide? Given the chaotic organization of the on-line version of In The Beginning, it wouldn't amaze me if I've simply missed something, but most of the easy answers seem to create more problems than they solve. For example, if the rift reached its peak width on the "Atlantic" side long before the "Pacific" side, then the plate could first reach a tipping point on the "Atlantic" side and start gliding towards the "Pacific." However, doing so would inevitably close up the rift on the "Pacific" side from both directions, which would of course interfere with ridge formation along the "Pacific" rift.
First, let's not forget that according to the model the rift is complete, world-wide, in about one hour! I'm no physicist, but it seems improbable that the pressure being released on one side of the planet will be enough to prevent pressure from being released on the other side of the planet an hour later, or that it would take less than an hour for the initial site to go from microscopic surface crack to 800-mile wide rift complete with elevated Mid-Atlantic Ridge.stipe said:I think you've left parts out of your model.

That point will generate the greatest pressures and erosion rates. The areas away from it will donate material and energy toward that point.
That initial tear is also the place that will allow underlying material an escape route because the pressure released there would physically deny the same pressure being released on the other side of the planet. This accounts for the slope that the hydroplates can slide on as uplift here is offset by slumping elsewhere.
Don't know. I'm still far from understanding what the original hypothesis is, so I can't begin to guess how changing it would affect things.stipe said:I'm beginning to suspect that Walt's assertion that the rift encircled the globe and met its own tail at some point is wrong. I've looked at those maps of the undersea ridges and cannot make them link up. I wonder how that change in hypothesis would alter things...
Actually, something just occurred to me. You don't get hydroplate pieces unless they are completely encircled by the rupture. A rupture that only partially splits a plate, even if it leads to the same 800-mile wide rift plus ridge, seems unlikely to be able to cause the two still-connected sides of the plate to slide apart (even if they had somewhere to go!).stipe said:I'm beginning to suspect that Walt's assertion that the rift encircled the globe and met its own tail at some point is wrong. I've looked at those maps of the undersea ridges and cannot make them link up. I wonder how that change in hypothesis would alter things...
Agreed. But the initial point of rupture would remain the focal point for a greater proportion of the energy released. This will automatically introduce an imbalance to the rest of the event..aharvey said:First, let's not forget that according to the model the rift is complete, world-wide, in about one hour!

The slope we have (upwelling of the mantle centered on the initial rupture point).aharvey said:Second, let me note that your last sentence at least sounds like you're ignoring the fundamental problem here: for a plate to slide, it needs at least three things, a slope upon which to slide, a mechanism to reduce friction enough to slide, and somewhere to slide to.
The Pacific basin is a large slump in response to the upwelling of the mantle under the Atlantic ridge.aharvey said:I'm not at all sure what object you think is "slumping elsewhere," but even if it's the hydroplate itself plus the crust and mantle below, increasing the slope in this fashion will not cause the hydroplate to slide unless there is somewhere for it to go i.e., "at the bottom of the hill."
The slumping probably accounts for this according to Walt. I don't have a firm enough grasp on the hypothesis to describe what's happening.aharvey said:Third, allow me to cut and paste a paragraph from my last link above: Given the chaotic organization of the on-line version of In The Beginning, it wouldn't amaze me if I've simply missed something, but most of the easy answers seem to create more problems than they solve. For example, if the rift reached its peak width on the "Atlantic" side long before the "Pacific" side, then the plate could first reach a tipping point on the "Atlantic" side and start gliding towards the "Pacific." However, doing so would inevitably close up the rift on the "Pacific" side from both directions, which would of course interfere with ridge formation along the "Pacific" rift. So, your explanation would prevent the formation of the MidOceanic Ridge wherever the plates would be sliding towards the rift (i.e., opposite all those places where the plates are sliding away from the rift).
Again, these two arguments appear to work against each other, namely: 1) the rift has an hour head start on the Atlantic side vs. the Pacific side, which means that rift expansion and ridge rising is further along enough on the Atlantic side to cause the plate to slide towards the not-so-far-along Pacific side, and 2) by the time the plate starts sliding, the rift on the Pacific side is big enough to give it somewhere "worthwhile" to go (but to be frank, even the 400 miles of a fully expanded rift is hardly enough to account for the distance between the continental margins and the middle of the Mid-Atlantic rise).stipe said:Agreed. But the initial point of rupture would remain the focal point for a greater proportion of the energy released. This will automatically introduce an imbalance to the rest of the event..
The slope we have (upwelling of the mantle centered on the initial rupture point).
The reduced friction we have (water escaping from the subterrainean chamber).
The place to slide we have (excavation from the rift as it extends to the other side of the Earth).
Here's the best I can come up with. In the section called The Origin of Oceanic Trenches (which, despite the title, seems to deal only with the origin of Pacific trenches), he says the following (with my emphasis added):stipe said:My uncertainty arisese from not quite being able to conceptualise where the tear in teh crust propogated to and if it came full circle. Like you I am having trouble figuring out how plates can slide given distances without being blocked by other plates. Have you read any of Walt's discourse that might suggest how fat plates slid?
In these examples, though, what's slumping? The hydroplate? If so, just because one side's high and the other side's low/slumping doesn't mean the plate will be able to go anywhere. If not, then where did all the hydroplate that used to be on top of the now slumping crust/mantle/etc. go?stipe said:I picked the South America example for an earlier post because it looked like a clear case of rift and uplift on one side with rift and slump on the other. The crash zone is there in the Andes. I would appreciate further input on the matter.
The Pacific basin is a large slump in response to the upwelling of the mantle under the Atlantic ridge.
Well, thanks for hanging tough on this. I'm not shy about asking Walt himself about the hydroplate theory, but I don't really want my first question to be "So what is it that the hydroplate says happened?"!stipe said:The slumping probably accounts for this according to Walt. I don't have a firm enough grasp on the hypothesis to describe what's happening.
stipe, this is critical: when you're talking about the events that form the foundation of the hydroplate model, you shouldn't really be referring to "the Pacific ocean," because that doesn't exist yet, so its floor can't really be sinking. Please restate the above sentence in terms of the hydroplate, oceanic crust, and mantle (as needed), since we're trying to figure out to which the Pacific Ocean floor corresponds!stipe said:Slumping is the Pacific ocean sinking as the Atlantic chamber floor rises.
I think you're missing the point. That quantity of granite is simply what would have to have been removed from the ten mile deep, 800 mile wide, 46,000 mile long rupture carved out of the hydroplate by the subterranean water escaping through the rift. Those are Walt's dimensions, I just calculated the volume and mass of the granite that used to be there. Interestingly, if you want to add granite from other sources to the world's sediment loads, you have to increase the amount of basalt somehow scoured off of the oceanic crust accordingly to keep the 65:35 granite:basalt ratio in Walt's model.stipe said:Interesting numbers though I don't think they make intuitive sense to me. Does the hydroplate model require all the granite deposits to be the result of erosion and deposition from the rupture? I wouldn't have thought so. The sliding hydroplates and their actions would account for a lot more.

When the rupture started the process of redistributing the mass of the Earth started. Mass was first removed from the Atlantic (region) which created instability balanced by pressure from below (the Pacific region .. ie the other side of the Earth.)aharvey said:stipe, this is critical: when you're talking about the events that form the foundation of the hydroplate model, you shouldn't really be referring to "the Pacific ocean," because that doesn't exist yet, so its floor can't really be sinking.

So everything on the Pacific side "slumped:" mantle, crust, and hydroplate? (Not a criticism, I'm just trying to be clear).stipe said:When the rupture started the process of redistributing the mass of the Earth started.

Not sure what you're trying to show here: is there a narrow ridge on one side of the Moon with a correspondingly narrow trench on the opposite side or something?stipe said:
The mass that is pulverized and disintegrated on the side of the moon facing us was replaced by material from the center of the moon causing the other side to cave in? Is that what you are saying?stipe said:The moon didn't have a subterrainean chamber. But when one side of the moon was pulverised the mass lost to disintergration was replaced by mass through the center and from the other side of the moon. This generated heat, molten rock, basaltic flows and a huge slump on the opposite side from where all the impacts centered.
