Evolution identifies older strata as being deposited before younger strata, so naturally older strata would be found below younger strata. The buckled strata moves over the unbuckled strata. The movement continues for miles. Buckled strata comes to rest on unbuckled strata. Flooding erodes topmost younger strata.
Older strata comes to rest on top of younger strata.
Never mind the obvious geology . . . . The 'Jurassic Era' thus becomes the 'Jurassic Environmental Zone.' 10. Floodwaters drown animals and wash their remains into other regions. Floodwaters elsewhere then wash 'older strata' drowned remains on top of the 'younger strata' remains. Creationist environment strata A and B can assume any vertical arrangement, since they are contemporary.
