How can older rocks be found on top of younger rocks in a cross-section?​

So If the older rock is sedimentary, such as a stream deposit, the layers will indicate which way was up when deposited. When you find this layer overturned on top of a younger rock, it’s likely part of a fold structure and should have a trend matching other rocks showing a fold.

You already know from surveys that the complete section of the area has a layer of A below a layer of B. If you find A above B, some event overturned it

There is a marker bed such as a layer of volcanic ash that records a single event in the area, then you have a reference point in time.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
