Final answer:
Inceptisols are young soils with minimal horizon development and are more developed than Entisols, found in a variety of settings such as steep slopes and young geomorphic surfaces.
Step-by-step explanation:
The soil order described by the student's question that exhibits minimal horizon development, is more developed than Entisols but lacks features of other soil orders, is found in a variety of ecological settings such as steep slopes, young geomorphic surfaces, and on resistant parent materials is known as Inceptisols.
Inceptisols are relatively young soils that have begun to show features of soil development and horizon formation. They often have O, A, and C horizons, are found in a wide range of ecological conditions, and may be present on various geomorphic landscapes. These soils are classified as having weakly developed subsurface horizons that are mainly formed due to weathering and biological activity.
Soil profiles of Inceptisols tend to be less developed compared to older, more mature soil orders. They represent an intermediate stage in soil development that may lead to more complex soil structures if given enough time and stable environmental conditions.
