Inceptisols (from Latin inceptum, beginning) are soils that exhibit minimal horizon development. They are more developed than Entisols, but still lack the features that are characteristic of other soil orders.
Soil is a thin layer of loose sediments (usually very fine-grained) and organic matter that lies above a layer of partly-weathered broken rock (called subsoil). Subsoil lies above the bedrock. The term regolith describes all of the loose, incoherent sequence of rock fragments, sand, alluvium, and soil that rests upon solid rock (also known as bedrock). Soil layers. Soils are made up of three layers and are thickest where they are older and in warm and wet environments. The layers are called horizons.
