Of course the Bible doesn't support any of that. You're not only twisting science; you're twisting the Bible too.
But in any case, stretching to five hundred years doesn't help you at all. There's no way for all that lithification to take place in such a short time frame. Multiple flood layers indicate multiple floods over a long period of time, with time between floods for drying, hardening, compaction, metamorphosis, etc. And between floods, life goes on, leaving tracks, burrows, etc. between the layers.
Flood geology doesn't come close to explaining all of that
No, creationists don't always teach the Bible, but water it down, pardon the pun, by leaning on 'science so named.'
You don't believe in sudden changes, because the scientific models are virtually static and not dynamic. As the apostle Peter says "they say that all things have continued as from the beginning" the change rates are static.
But a few modern storms and earthquakes will get people to think differently than the sleepy everlasting story of mini progressions.
