The soils of the plains have not been derived Correct Answer Only from the rocks existing locally
The soils of the plains have not been derived only from the rocks existing locally. Plains are associated with high productivity due to the generally reliable summer precipitation, a long growing season, and deep, fertile soils. Productivity is greatest in the eastern region (tallgrass prairie), followed by mixed grass, then shortgrass prairie.
