Tell me, duordi, what is the denser liquid material they are discussing in that website you referred to?

How many mountain peaks do you know that are not windy?Arikay said:Out of curiosity, why did the erosion cut such a windy canyon?
How many mountain peaks do you know that are not windy?
But wind impacts all serfaces.
Only waves can vary erosion with elevation.

The classic scale for hardness was published in 1822 by Frederick Mohs, an Austrian mineralogist who got the basic concept from scratch tests performed routinely by miners. Since Mohs published the scale, it bears his name rather than that of the unknown genius who thought of it. The scale selects 10 minerals as standards, arranging in order of increasing hardness. These are, as most of you probably know:
1 = Talc 2 = Gypsum 3 = Calcite 4 = Fluorite 5 = Apatite (fluorapatite) 6 = Orthoclase 7 = Quartz 8 = Topaz 9 = Corundum 10 = Diamond These minerals were selected for their abundance, as well as their differing hardness. The scale is uneven. For example. diamond at 10 is much harder then corundum at 9, while fluorite at 4 is only slightly higher than calcite at 3.
A more limited but practical scale can be easily and cheaply obtained by observing that
....your fingernail has a hardness of 2.5, ....a penny has a hardness of about 3.5, ....glass and a steel nail have nearly equal hardnesses of 5.5 and ....a streak plate has a hardness of 6.5.

Vastavus said:In your picture, (Of Bryce Canyon) the formations are far to delicate to be formed by the destructive forces of a global ocean, the "hoodoos" as they are called, would have been destroyed. It was a mixture of water, ice, and a long period of time. It didn't happen instantly.

How did the wind and ice know to put that neck in every structure at the same exact height
And make the separation between the pillars the same distance
How would the waves to this?
Are you going to tell me the rock grain runs vertically and horizontal at the same time
If the rock was really weak at the neck it would not be common to have it remain in so many places so identically without breaking off and falling.
But if the erosion was by water and the rock strength is relatively constant then the amount of material removed and the tunneling between the peaks would be almost exactly the same as it depends on the number and condition of wave strikes.
The size of the average wave can even be determined by the distance between columns.
The necks would be as strong as the rest of the structure causing the structure to be physically sound and consistent in its form.
This picture is not a product of wind and ice.
Thank you for your help!
A very good question.Arikay said:Curvy.
Along with that, how did the flood lay down all the different layers in the canyon, allow them to harden, and then erode them away?
How did it make the vertical devisions?notto said:Because not all of the layers have the same density or strength. Some will erode more on every 'structure', some less. Whether it is water, wind, or ice - the pattern isn't surprising. Not all of the layers are the same material.
How did it make the vertical devisions?
Are you going to tell me the rock grain runs vertical and horizontal at the same time?
This is caused by the way waves crest at certain distances after a first impact.

The liquid molten layer below the earths crust and the oceans crust is what you are speaking of I believe.HRE said:Tell me, duordi, what is the denser liquid material they are discussing in that website you referred to?
The picture was nice.Vastavus said:Look at my post on the last page, click the link. It will answer your questions.

But this idea would cause a random condition, not a consistent distance.notto said:Or, erosion started through cracks and left pillars standing. Something we can still see happening today.
I don't think your wave crest explanation explains the evidence. Can you be a bit more specific? Where did you get this information?
duordi said:But this idea would cause a random condition, not a consistent distance.
The more vertical columns you have in a row the more the measurement between the columns is remarkably the same because the redundance of the wave pattern will be reinforced due to wave interference.

duordi said:The liquid molten layer below the earths crust and the oceans crust is what you are speaking of I believe.
The continents "float" on it, and so do the oceans.
The crust under the oceans is thinner.
Some believe the dirt in land is lighter then water and floats higher.
Some believe the land is just thicker and so it floats higher like an iceberg floats higher out of the water then compared to thin surface water ice.
But regardless continents move until they reach an equilibrium as they float in the magma layer.

I can see the picture.notto said:Can you provide these measurments that are remakably the same? What was your sample size? What were the measurments? Where is the data?
duordi said:I can see the picture.
How much more do I need to prove it wasn't random.
Unless of course you want to calcualte the average wave length of the surface water.
