One process that can disturb layers of rocks and prevent fossilization is tectonic activity, which includes events like earthquakes and volcanic eruptions. These geological processes can cause upheaval, folding, or faulting of rock layers, disrupting the conditions necessary for fossil formation. Additionally, erosion can remove sedimentary layers, further exposing and destroying potential fossils before they can be preserved. Other factors, such as weathering and extreme environmental changes, can also hinder the fossilization process.
An animal fossil can be buried in sedimentary rock layers such as sandstone, shale, or limestone that have accumulated over time. The fossilization process occurs when the remains of an animal are buried quickly after death, protecting them from decay and allowing for the formation of a fossil.
Shells can become preserved in sedimentary rock through a process called fossilization. This occurs when a shell is buried by sediments and then mineral-rich groundwater seeps into the pore spaces of the shell, replacing the original material with minerals. Over time, the shell hardens into rock, preserving its shape and structure.
The deluge fossil formation theory, also known as the catastrophic burial theory, suggests that fossils are formed rapidly through catastrophic events like floods. This theory is supported by evidence showing that many fossils are found in sedimentary layers, suggesting sudden burial. However, while this theory is accepted in some cases, the process of fossilization can also occur through gradual processes like sediment accumulation and mineral replacement.
Fossils may be absent in layers c and e due to several factors, such as environmental conditions that were not conducive to fossilization, like high levels of erosion or sediment displacement. Additionally, these layers might represent periods of time when no organisms existed, or when existing organisms did not have the right conditions for preservation. It's also possible that the layers were subjected to geological processes that destroyed any fossils that may have existed.
Fossils form primarily through the process of sedimentation, where organic remains are buried under layers of sediment, which gradually harden into rock. Over time, minerals from groundwater seep into the remains, replacing organic material and preserving the shape of the organism. Conditions such as rapid burial and low oxygen levels help prevent decay, increasing the likelihood of fossilization. Factors like the type of organism, environmental conditions, and geological processes also influence the formation and preservation of fossils.
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
the four rock layer disturbances are: tilting, intrusion, faults, and folding

Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.
Earthquakes, landslides, and volcanic activity can all generate forces that may overturn rock layers. These forces can shift and disturb the layers, causing them to overturn or fold.
The standard theory is that fossil fuels formed millions of years ago from the remains of dead plants and animals that were buried in sedimentary rock layers. Over time, heat and pressure converted these organic materials into coal, oil, and natural gas. This process is known as fossilization.
Shells can become preserved in sedimentary rock through a process called fossilization. This occurs when a shell is buried by sediments and then mineral-rich groundwater seeps into the pore spaces of the shell, replacing the original material with minerals. Over time, the shell hardens into rock, preserving its shape and structure.

Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.
