The process of "overthrusting" occurs when tectonic forces push one rock layer on top of another, causing younger rock to be placed beneath older rock. This can lead to a reverse order of rock layers in a geologic formation. Another process, called "faulting," involves the movement of rock layers along a fault plane, which can result in the displacement of younger rocks below older rocks.
It is called "overturned stratigraphy" or "inverted stratigraphy." This occurs when the rocks have been folded or overturned due to tectonic forces, resulting in the older layers appearing on top and the younger layers underneath.
The layers of rock above the coal are younger, while the layers of rock below the coal are older. This is because sedimentary layers are deposited in a chronological sequence with the oldest rocks at the bottom and the youngest rocks at the top.
When the surface of new rock layers meet a much older rock beneath them, it is called an unconformity. This represents a gap in the geologic record due to erosion or non-deposition between the older and younger rocks.
Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
older because it is at the bottom and the ones on top are younger than the bottoms

Older rocks that lie under younger rocks are called bedrock. Bedrock forms the solid foundation upon which younger rocks are deposited and can provide valuable information about the geologic history of an area.

Principle stating that older rock layers are beneath younger rock layers.

A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
