The two main ways that rock layers can be disturbed are folding, which results from compressional forces causing layers to bend, and faulting, which occurs when rock layers break and move along fractures. These processes can create geological structures such as anticlines, synclines, and faults.
Undistributed rock layers may indicate that the layers have not been disturbed or deformed from their original horizontal positions. The oldest rock layers are typically found at the bottom of a sequence, while the youngest rock layers are found at the top, following the principle of superposition in geology.
One indication that rock layers have been disturbed is when they are no longer in their original, horizontal position. Folding, faulting, or tilting of rock layers can suggest tectonic activity, such as earthquakes or mountain-building processes, that have disrupted the original layering.
Fossils can be used to determine the relative age of rock layers by comparing the types of fossils found in different layers. Fossils of organisms that existed for a short period of time can be used to date layers of rock containing them. Geologic features such as fault lines and unconformities can also help determine the relative age of rock layers by showing where layers have been disturbed or eroded.
The principle of superposition in geology states that in an undisturbed sequence of sedimentary rock layers, the oldest layers are at the bottom, and the youngest layers are at the top. This means that if the layers have not been disturbed by tectonic activity or erosion, their original chronological order can be used to understand the relative ages of the rocks. Consequently, superposition helps geologists interpret the geological history of an area by analyzing the sequence of deposition over time.
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
It states that younger rocks lie above older rocks if the layers have not been disturbed.

Geologists know that rock layers are undisturbed by examining the relationships between the different layers. If the layers are parallel and show no signs of folding, tilting, or faulting, they are likely undisturbed. Additionally, the presence of index fossils can help date the layers and determine if they have been disturbed.

4 ways are folding, tilting, intrusions, and faults. Hope this helped :)
