Solution(By Examveda Team)

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.
