According to the law of superposition, younger layers of rock are generally found above older layers of rock. however, there are locations where older layers are found above younger layers. which of the following can cause this to happen?
a.
rock layers can overturn as they are folded.
b.
during uplift, rock layers can tilt enough to overturn.
c.
older rock layers can slide above younger rock layers along faults.
d.
all of these

ALL OF THESE following can cause this to happen.

D.  all of these

Explanation:

According to the law of superposition, the younger rocks are placed on the older rocks because of the tectonic forces acting on the rocks. The tectonic forces can erupt or they disrupt the rock layers in a no of ways like folding, faulting and the uplifting.  

The rock layers are overturned due to the fold, the tectonic forces which are at the largest scale move the lithosphere plates, also cause bending, wrapping and folding and the fracturing of the rocks. The earth's crust at the continental, regional and the even local scales.
