Inceptisols are characterized by their weakly developed horizons, which sets them apart from more mature soils. These soils generally form in a variety of environments and are recognized by their relatively young developmental stage in terms of soil formation. The "weakly developed horizons" implies that Inceptisols have not yet undergone significant profile differentiation, meaning they do not exhibit the distinct layering or horizon differentiation found in more mature soil types such as Ultisols or Mollisols.

This intrinsic property reflects the early stage of development where weathering and organic matter accumulation processes are still ongoing, leading to a soil profile that lacks the pronounced horizons typical of older soils. Additionally, the characteristics of Inceptisols often include a higher degree of variability in texture and color, further emphasizing their less developed state compared to soils with stronger horizon development. Thus, the choice highlighting their weakly developed horizons accurately captures a fundamental aspect of Inceptisols.
