The U.S. soil classification system is known as Soil Taxonomy and it is hierarchical, consisting of six categories from soil series to soil order. The other options are incorrect. Option A is partially correct, but it is not the main reason for having regional classification systems. Option C is incorrect since Soil Taxonomy has been updated and revised since its initial publication in 1975. Option D is incorrect because while the soil-forming processes are considered, the classification system is not solely based on pedogenic regimes or climatic regions. Option E is also incorrect since soil order is not based on the priority of the soil.
