Match the soil order to its defining characteristic. Ultisol Oxisol Mollisol Vertisol Aridisol Entisol Inceptisol Extremely weathered due to consistent precipitation and time. Fe and Al oxides common. Highly weathered, often found in older portions of the Ozarks. Time and Climate dominated Little horizonation, enough to fall out of another order. High shrink-swell clays are common. Crack when dry, expand when wet. Lack of diagnostic horizons. Not necessarily young. Formed under conditions that allow annual root turnover at deep depths. Climate dependent. Formed under a lack of precipitation. Physical weathering is common. .
