Could a younger layer of sedimentary rock ever be found under an older layer How do you think this could happen?

Answer 1

Yes, a younger layer of sedimentary rock can be found beneath an older layer due to geological processes such as faulting, folding, or erosion followed by deposition. For instance, if tectonic activity pushes older rock layers upwards, younger sediments can be deposited on top of them, or if an area undergoes significant erosion and then new sediment is deposited, the sequence can be inverted. This phenomenon is often seen in complex geological formations where layers have been disturbed.
