We know the continents moved and mountains raised in many cases. How fast is not known by science. The flood is not something science deals with knows about, or has anything to say about.
Yes they do...so? What has that got to do with the KT era worldwide flood of Noah?
Break? Why would we see that? If mankind and most animals could not leave remains in the former nature why would we expect some 'break'? We started to be able to leave remains as the nature allowed.
The same nature in the past...no evidence...ZZzzzzz
What claim? That the bible indicates nature was not the same, and therefore all things we know that happened like uplift, drift..etc could have been rapid??
Science doesn't know what the nature was like so either we admit that and just be ignorant, or we avail ourselves of the actual record God left us of that time.
Here are some reasons listed as to how the bible record indicates a different state in the past than we now have.

What Hebrew dates are you talking about and why?
There is NO DNA from pre KT layer is there? Sorry, but we just do not know modern genetics was the same as what we had then. Try talking from knowledge rather than hunches eh?
