I see noone bothered to refute Quasar's latest bulb of nonsense during my holiday. Well, on we go:
Quasar1011 said:
Secondly, those distinctive stripes you mention, are often not parallel to the ridge itself.

So you have a much simplified idea of how plate tectonics works, find that reality isn't that simple, so the theory must be false?
The textbook example is of the stripes in the Reykjanes Ridge near Iceland. But often, the stripes run perpendicular to the ridge, or show no discernible pattern at all.
Show a place where they run perpendicular.
The spreading of the mid-Atlantic ridge has been measured all along its length. There are some parts of the ridge that show no current spreading at all!
So? Why should the CURRENT rate matter?
And other parts of the ridge are moving the adjoining plates apart, at rates that are so slow that a date of 100 million years is a gross overstatement.
Again, you make the dumb mistake of assuming a static system
So, we have "halted growth" as observed fact.

Your hair grows. Thus, you grow. Thus, you'll be at least 8 feet tall if you reach the age of 80.
That claim is about as logical as yours
The fact that South America is no longer joined to Africa, is evidence of a disruptive event which accelerated growth.
btw, 'growth' is an extremely dumb term to use when talking about an ocean. Grwoth suggests that there is some biological process, but there isn't.
Obviously, we are disagreeing about the timing of that event.
If you insist on calling something that took a few hundred million years an 'event' - do so. But do not be surprised if we laugh at you. Please define the 'disruptive event' - was it the first ever fault to reach the surface? The first volcanoe along the grabenbruch? The first ever earthquake along the later fault line? The first influx of salt water into the graben?
I think even you'd agree, that a crack in Pangaea which eventually led to its splitting apart into separate continents, is a "disruptive event".
Nope, it is a process.
The only rock to be swept away, was that rock which water or mud was eroding. This can result in both vertical canyon walls, as well as V-shapes. See my next paragraph.
Again, my dear Quasar - why was this part of the rock swept away and the stuff the visitor's center rests on today wasn't? Why wasn't the material swept away that today forms the canyon walls? the debris at the foot of the near-vertical walls?
This doesn't match the observed evidence (see photo at end of post).
false - you claim that a soft sediment and a hard consolidated rock have the same properties. Obviously, this is nonsense. If you throw a piece of sandstone against a window, it will break. If you throw a lump of hardly compacted ash against it, the window will stay intact. Thus, the properties of the two materials are vastly different.
The canyon that was observed to form on Mt. St. Helens in 1982, has some vertical walls.
False - it has tiny sections of 'walls' where the current undercut a cliff. These sections are extremely instable and erode away quickly. Quite different from the vertical walls of the Grand Canyon, which look the same today as they did when the first pictures were drawn.
I discovered, however, that it was technically not water that cut that canyon, but a mudflow. However, the mudflow cut through some solid rock.
False, it cut through hardly consolidated ashes and thin lava flows. This is totally different from a solid 100 foot sandstone layer.
So we have an observed case where material (water or mud) cut a canyon with vertical walls, in less than a week.
As shown - false. Even if 2% of the walls of that 'canyon' are near-vertical, this doesn't in any way compare to the shape of the Grand Canyon.
There are other such canyons as well. Burlingame Canyon near Walla Walla, Washington, formed in 1926 in 6 days (see photo at end of post).
One look at these photos shows IN EACH SINGLE ONE a small erosional wall in a soft sediment or a layered sediment group with significant soft layers (marls). None of the walls is comparable in steepness to the Grand Canyon, and none is comparable in size to the Grand Canyon.
Seems you are prone to shoot yourself in the foot provided you cna get the firepower - you show that in soft ysediments and layered sediments ereosional walls look significantly different from the Grand Canyon. Congratulations
This canyon is 120 feet deep in places. Six days of runaway erosion removed around 150,000 m3 (five million cubic ft) of silt, sand and rock.
There we go - can you please explain how a 120 foot packet of sediments that contain both sitls, sands and 'rocks' (thin sandstone layers or conglomerates or what?) is in any way compareble to a several hundered feet thick SINGLE sandtone bar?
Also, Providence Canyon near Lumpkin, Georgia, formed in 1846 due to heavy rainfall, and continued to grow through the next several decades. There are 9 finger-like canyons in this system, some as deep as 160 feet; as wide as 600 feet, and as long as 1,300 feet. By 1971, this area was set aside as Providence Canyon State Park, and is often called Georgia's little Grand Canyon (see photo at end of post).
Again, much softer sediments

This starts to get really boring.....
We've never observed a canyon actually cut with a little bit of water, over a long period of time.
But we do, constantly. it is just that the likes of you do not understnad that it takes more time that you can imagine
But we have observed, in the last 200 years, canyons that were cut with a lot of water, in a little bit of time.
and look significantly different from the Grand Canyon.......
Study the photos at the end of this post. None of those photos were possible as recently as 160 years ago, because the canyons had not yet formed!
Yup. And all show typical speedy erosion is soft sediments. Quite different from e.g. the up to 350 feet thick Coconino Sandstone, the up to 700 feet thick and rather massive Redwall limestone 1, the up to 100 feet thick Undivided Dolomite.........
an explanation of the layers can be found here:

You keep throwing out geological evidence of rapid canyon formation, claiming irrelevance.
Yup, all your exaplmes come from very different sediments (much softer and subdivided).
But extinctions within the fossil record are evidence.
non sequitur.....
The mid-oceanic ridge is evidence of it.
of what - extionctions? rapic canyon formation? get your grammar straight enough for me to understand, please.
There is also a written account of a worldwide hydrological and geological disaster; it was observed (just like rapid canyon formation has been observed). You throw out all the evidence, because the written account happens to be in the Bible.
Yup - I do. Since the bible is neither peer reviewed, nor has it proven in any way to be more that goatherder tales and fishermen tales and later additions by priests. I an sure you know that fishermen like to tell big tales?
Therefore, why don't we listen to a non-Biblical source: the native American residents of the Grand Canyon?
According to the Havasupai Indians who live in its deep gorges, the Grand Canyon originated in the following way:
Before there were any people on earth there were two gods. Tochapa of goodness and Hokomata of evil. Tochapa had a daughter named Pu-keh-eh, whom he hoped would become the mother of all living. Hokomata the evil was determined that no such thing should take place, and he covered the world with a great flood. Tochopa the good felled a great tree and hollowed out the trunk. He placed Pu-keh-eh in the hollowed trunk and when the water rose and flooded the earth she was secure in her improvised boat. Finally the flood waters fell and mountain peaks emerged. Rivers were created; and one of them cut the great gushing fissure which became the Grand Canyon. Pu-keh-eh in her log came to rest on the new earth. She stepped forth and beheld an empty world. When the land became dry, a great golden sun rose in the east and warmed the earth and caused her to conceive. In time, she gave birth to a male child. Later a waterfall caused her to conceive and she gave birth to a girl. From the union of these two mortal children came all the people on the earth. The first were the Havasupai, and the voice of Tochopa spoke to them and told them to live forever in peace in their canyon of good earth and pure water where there would always be plenty for all!"
Wow, two gods? Not one? THIS CONTRADICTS YOUR BIBLE STORY MASSIVELY!
How long does it take for a fossil to form? If a creature is not quickly buried, and sheltered from weathering, it will decompose, rather than form a fossil. This is a physical, chemical, and biological process. Will you agree that fossils form in sediments?
Where are you going - trying to impress people with commonplaces?
If the entire world was under water at some point, wouldn't fossils form in sedimentary layers?
Sure would - so?
And some of those layers would be on mountaintops, just as is observed.
Maybe - depends on circumstances.
Now, if those mountaintops have been there millions of years, the fossils would have eroded away.
Please go and measure the erosional rates in the Rocky Mountains, the Cascades, the Dolomiti, Chalk Alps etc
