Answer 1

=================================
A thrust fault would also create this anaomoly
an Island is propelled by plate tectonics
The lower mantle dives into the subduction zone scraping off the island such that it collides with a continental mass such as California's Coast line.
The collision buckles older layers and thrusts it up over a more recent layer.s
Creating a thrust fault in which the older layer lies on top of a more recent layer.

================================

Answer 2

This happens in an overthrust, an example of which is the Idaho-Wyoming Overthrust Belt. Tectonic forces force strata from one side of the fault over top of the other. In some cases, one side has been flipped completely upside down so that the oldest layers are on top.

Young Earth Creationists should note that even IF all those sediments could be deposited in an amazingly short period, one layer would still be older than another. Just by hours instead of millions of years. But the laws of physics should still apply to some extent, depending on just how much hocus-pocus you think might have been used to trick the many thousands of brilliant and well educated scientists who dedicated their careers to the subject over the past several hundred years.

Answer 3

How deep is this cross section?

People move rocks. Natural forces such as upthrust moves rocks.

I was out in Pennsylvania and toured some caves. The original limestone layers were flat, obviously, since it's a sedementary rock. You don't lay down sedementary rock sideways. But since it was laid down, natural forces have twisted and folded the layers until they look like waves.

Answer 4

You would be looking at an upturned fold. (Syn-formal Anticline). The sediments basically have been bent over so much that they have folded back onto themselves. If you knew a bit about structural geology then this would be apparent.

Answer 5

Explain a probable cause for th------- WHAT?


Permutations? Disparity?

Suppose you check Genesis 6-9...I think it's thereabouts that something about a flood is mentioned. That's one of many theories.

It wouldn't be out of the question for a natural disaster (flood, earthquake, pestilence, deep freeze) to cause massive shifting in rock layers.

Answer 6

Land slides might have flipped the rocks

Or a tsunami could have flipped the rock body

or unloading of a laccolith or batholith could have placed older on top of younger rock
