Final answer:
The limited horizonation in the soil type mentioned is associated with the soil being young and undeveloped, which means it has not yet progressed through stages that would produce the well-defined layers seen in older, more mature soils.
Step-by-step explanation:
The limited horizonation in the soil type mentioned is because C) The soil is young and undeveloped. Soils develop distinct layers known as horizons over time due to a combination of factors including parent material, climate, organisms, topography, and time. The degree of soil horizonation increases as the soil ages, with mature soils displaying additional layers beyond the basic O, A, and C horizons typically found in immature soils.
Young soils are strongly influenced by the composition of the parent material and can rapidly develop horizons and character. However, as soils continue to age, the effects of weathering, erosion, and other soil-forming factors can balance out, leading to an equilibrium where significant changes to the soil's physical structure slow down or cease. Factors such as poor drainage could lead to accumulation and preservation of organic matter, which affects soil color and texture, but they do not directly contribute to the soil being younger or less developed.
Based on the information provided, soil erosion, weathering patterns, and drainage do play roles in soil development but these do not indicate that the soil with limited horizonation is young. The correct answer to the soil's limited horizonation is tied to the soil's age rather than its drainage, level of erosion, or degree of weathering.
