The answer is Pennsylvanian. I worked on this before. The Pennsylvanian era is a subperiod of the Carboniferous Period. i really hope this helps :)
The depth of a soil profile is dependent on the type of parent material. the more easily weathered the parent material, the deeper the soil profile. select one: True.
“Soil profile is defined as the vertical section of the soil from the ground surface downwards to where the soil meets the underlying rock.”
- The soil is the topmost layer of the earth’s crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons.
- Soil profile helps in determining the role of the soil as well. It helps one to differentiate the given sample of soil from other soil samples based on factors like its colour, texture, structure, and thickness, as well as its chemical composition.
- here The parent material of a soil determines the original supply of those nutrient elements that are released by physical and chemical weathering and influences the balance between nutrient loss and retention. Organic acids and exudates produced by microorganisms and plants enhance the weathering of minerals and the release of nutrients.
