Why are some rock layers thicker than others?
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.
What principle tells us that rock layers separated by a valley are assumed to have once been continuous?
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.
Where was the eroded material from the Canadian shield deposited?
The eroded material from the Canadian Shield was primarily deposited in surrounding areas, including sedimentary basins such as those found in the Great Lakes region and the Hudson Bay. Over geological time, sediments were transported by rivers and glaciers, accumulating in low-lying areas. Some materials also contributed to the formation of sedimentary rock layers in adjacent regions, such as the Western Canada Sedimentary Basin.
Where are slightly tilted rock layers formed?
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.
Broad areas of folded rock layers that resemble a bowl turned right-side up are called?
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.
Where will the layers of soil most likely be the thinnest?
where will the layers of soil most likely be the thinnest
What type of dating involves matching up layers of rocks from two different areas?
Correlative dating matches that definition.

Where would you find bugs?
Under rocks & leaves, undisturbed areas.
Where is coal deposited?
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.

Can you use the word wetlands in a sentence?
Migration into undisturbed areas of airfields can be encouraged and ponds and wetlands conserved and repaired.

What process happened in the landfill site?
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.
What do you call areas of deposited sand or silt on river bends?
sand bars
What sediment is deposited in bodies of water and other low lying areas?
Deposition
Where is silt and soil deposited?
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.
