Summations Only

You left out an explanation of a critical question. How would a fludde produce narrow, deep, "incised meanders" as shown in the image you posted? Meanders form where the flow is slow. For complicated but well-understood reasons, they erode the outer bank and deposit on the inner bank.In soft unlithified deposits, that erosion/deposition moves the main channel outward and increases the curvature of the bend. The meanders don't get deep because they are moving horizontally over the terrain so they don't hang around on each particular plot so it can't erode the bottom much.The end result is often an oxbow lake and cutting a new main channel. Happened all the time on Mark Twain's Mississippi. But if the meanders are on hard lithified rock, the erosion/deposition cycle is very very slow. The meander spends much more time on each plot of land. It erodes material from its bottom, very slowly, and carries it downstream. As the water sinks lower the old outer and inner banks move down, and the meander doesn't erode the former banks any more. So the meander eventually gets deep with near-vertical walls.Therefore the image above is of meanders cut through pretty hard rock.

Everyone has difficulty grokking huge or tiny numbers. Faith has a triple dose of that difficulty.

Yes. And erosion causes other things. Such as flat plains where the material is deposited.

It's crucial to the point you tried to make. You denied erosion causing flat surfaces. You listed some other things erosion causes, implying those are all that it causes. I pointed out that ain't so.You can list other things caused by erosion till the cows come home, it still won't be a refutation of erosion causing flat surfaces. Or even relevant. Edited by JonF, : No reason given.

Your uninformed opinion is neither evidence nor refutation.

You have lost the thread.Edge wrote "All of these are intermediate products. The ultimate product of erosion is a coastal plain." You replied with a list of things caused by erosion omitting "coastal plain". Implying that erosion does not produce flat surfaces.OThat is what I am addressing.

I just replied to what you wrote. If you don't want to discuss a topic don't raise it. If

I provided the context. It was Edge saying that erosion ultimately causes flat plains. Which you denied.

OK.

For one thing, the volcanism wasn't under water. There's distinct and obvious differences between lava solidified under water and in the air. So it was after the Fludde receded.
