The answer is: Relative dating
Rock layers can vary in thickness depending on factors such as the amount of sediment deposited, the duration of the deposition process, and local tectonic movements. In areas with high sedimentation rates, thicker rock layers may form compared to areas with lower sedimentation rates. Geological processes such as faulting and folding can also influence the thickness of rock layers.
The principle that indicates rock layers separated by a valley were once continuous is called the Principle of Original Continuity. This principle suggests that sedimentary layers are deposited in continuous sheets over large areas. When a valley forms, it can erode through these layers, but the original continuity of the layers prior to erosion implies they were once part of a larger, uninterrupted sequence.
Slightly tilted rock layers typically form in areas subjected to tectonic forces, such as along fault lines or at convergent plate boundaries. These forces can cause the Earth's crust to deform, resulting in the tilting of sedimentary rock layers that were originally deposited horizontally. Additionally, geological processes like uplift and erosion can also contribute to the tilting of rock formations over time.
Such structures are known as anticlines. They form when rock layers are compressed and folded upward, creating a dome-like structure with the oldest rocks at the center and progressively younger rocks toward the edges.
Sediment is typically deposited in bodies of water and low-lying areas during flooding events, when the water flow slows down and sediments carried by the water settle out due to gravity. Sediment can also be deposited gradually over time through erosion and weathering processes.
where will the layers of soil most likely be the thinnest
Correlative dating matches that definition.

Under rocks & leaves, undisturbed areas.
Coal is formed from the remains of plants that lived in swamps and marshes millions of years ago. These organic materials were buried under layers of sediment and compressed over time. Coal deposits are typically found in areas where these conditions existed, such as former swamps and wetlands.
Migration into undisturbed areas of airfields can be encouraged and ponds and wetlands conserved and repaired.

Deposition
In a landfill site, trash is collected and deposited in designated areas. The waste is then compacted to conserve space, and layers of soil are added to cover the trash. Over time, natural decomposition processes break down the waste.
Silt and soil are typically deposited in areas near water sources such as rivers, streams, and lakes. They settle in these areas due to the action of water carrying and depositing sediment as it flows. This process is known as sedimentation.
Such structures are known as anticlines. They form when rock layers are compressed and folded upward, creating a dome-like structure with the oldest rocks at the center and progressively younger rocks toward the edges.
