Soil chemistry, important to agriculture and natural plant ecology, is related to bedrock composition because rock weathering contributes to soil formation. GIS Maps / Data. They can then use the results to optimize land use and management decisions based on where the sample was collected. In most places in Maine, the bedrock is concealed by a thin veneer of unconsolidated sediment (mainly deposited by Ice Age glaciers), soil, and vegetation. Moderate 4.3 (90) Kisatchie National Forest. By looking at places where the bedrock is exposed at the surface, geologists identify areas where the rocks are similar, and infer contacts between rocks that are different. Bedrock wells are drilled below the topsoil and groundwater into bedrock, tapping the cracks in the rock that carry water deep underground. Bedrock is made up of igneous, sedimentary, or metamorphic rock, and it often serves as the parent material (the source of rock and mineral fragments) for regolith and soil. Press question mark to learn the rest of the keyboard shortcuts.
