Oh, no, you don't --- not this boy.
What's that old saying?
- Never argue with an atheist --- he will drag you down to his level, then beat you to death with experience.
Example: without the hydrological cycle, then there will be no plate tectonics.
You could not separate the two.
Oh my. Someone please ask him to "flesh" that point out a bit.
(This would be interesting if he'd actually say something in detail about this, but past experience has indicated no such pleasure will be achieved here.)
I don't care what is the default position. We are talking about science.
If I went out into the woods and dragged a log for 30 yards, then set the log down; and later someone notices that the log seems to be moving at the rate of 1 inch per year, he may [wrongly] conjecture that that log as been around for at least 1080 years.
Huh!? How!?
Yes we are, and Thus you should respect the default position of SCIENCE!!!
This is also why the Noah's Flood is so critical. No Noah's Flood, no current earth. I guess AV have put out one challenge along this thread.
I would say wind
Evidence for water on Earth during the planet's first 500 million years is now overwhelming, according to Harrison.
"You don't have plate tectonics on a dry planet," he said.
Strong evidence for liquid water at or near the Earth's surface 4.3 billion years ago was presented by Harrison and colleagues in a Jan. 11, 2001, cover story in Nature.
Generation of plate tectonics from lithospheremantle flow and voidvolatile self-lubrication

Abstract:
The formation of plate tectonics from mantle convection necessarily requires nonlinear rheological behavior. Recent studies suggest that self-lubricating rheological mechanisms are most capable of generating plate-like motion out of fluid flows. The basic paradigm of self-lubrication is nominally derived from the feedback between viscous heating and temperature-dependent viscosity. Here, we propose a new idealized self-lubrication mechanism based on void (e.g., pore and/or microcrack) generation and volatile (e.g., water) ingestion. We test this voidvolatile self-lubrication mechanism in a sourcesink flow model; this leads to a basic nonlinear system which permits the excitation of strikeslip (toroidal) motion (a necessary ingredient of plate-like motion) out of purely divergent (i.e., poloidal or characteristically convective) flow. With relatively inviscid void-filling volatiles, the voidvolatile mechanism yields a state of highly plate-like motion (i.e., with uniformly strong plate interiors, weak margins, and extremely focussed strikeslip shear zones). Moreover, the voidvolatile model obeys a chemical diffusion time scale that is typically much longer than the thermal convection time scale; the model thus complies with the observation that plate boundaries are long lived and survive even while inactive. The voidvolatile model of self-lubrication therefore predicts self-focussing shear zones, plate generation, and plate-boundary longevity through what has long been suspected to be a key ingredient for the existence of plate tectonics, i.e., water.

I do not think you have shown this to be case good sir. Please provide the evidence why Noah's flood is required for a current earth.
So what if it is? It's a VERY, VERY small part of the cycle.juvenissun said:Take a look on what kind of gas volcanoes erupt? Mostly water. Would you say those water is not part of the water cycle?
???????????????????The earth is "created" with the water cycle in function.
Gee, they don't have wind erosion and do not have plate tectonics.. If we got some enormous fans big enough to create a wind, suppose we could initiate plate tectonics there?Take a look on Venus and Mars. They do not have water cycle, and they do not have plate tectonics.
You know, juvenissun, you could stand to explain yourself for once. I asked for you to explain how the water cycle has an effect upon plate tectonics. I did not ask for you to just repeat the assertion all over again.You are surprised because you only see a simple version of the water cycle. Take a look on what kind of gas volcanoes erupt? Mostly water. Would you say those water is not part of the water cycle?
And there is a deeper side of it. The earth is "created" with the water cycle in function. Take a look on Venus and Mars. They do not have water cycle, and they do not have plate tectonics.
This is also why the Noah's Flood is so critical. No Noah's Flood, no current earth. I guess AV have put out one challenge along this thread.
In science, there is no such thing.
Then clearly you understand nothing about science. You see, in science there is something called a null hypothesis. The null hypothesis is the default position: experiments are performed and data collected in an attempt to reject the null hypothesis. Now, when introducing some new positive claim, the default position is always that it isn't true: the null hypothesis is that the positive claim is false.In science, there is no such thing.
Again, what kind of evidence you like to see?
Indeed. If only. However, I still object to the idea that this has anything to do with the hydrologic cycle, except in a very peripheral manner. Water may well be necessary for plate tectonics, but I don't see why a hydrological cycle would be necessary. That is, if the planet is frozen, so that no liquid water flows, but there is lots of water in the mantle and lower crust, might not the same basic effect be achieved?But surely in a liberal reading of the role of water in the lithosphere one could reason that water anywhere on earth is part of the "Hydrologic Cycle", so as not to belabor an overly pedantic point.
Interesting indeed.
(Now if only Juvenissun would have provided this interesting information so we wouldn't have to provide it for him!)
Why is there no cracks along the track?
