A soil profile is a vertical section of soil that ranges from the surface to the bedrock. Each layer of a soil profile is referred to as a soil horizon.Horizon O is the top layer, where organic material is presentHorizon A is top soilHorizon B is subsoilHorizon C contains weathered rock.
A is the layer of the soil profile in which most organic material is found.Specifically, there are five layers in the soil profile. The first, A layer of organic matter claims the first two inches and contains plant debris. The second, A layer of surface soil comprises the next ten inches down. Below it will be found the third, B layer of subsoil containing aluminum, clay, iron and organic compounds and going down 30 inches; the fourth, C layer of parent rock going down 48 inches; and the fifth, final, R layer of bedrock.
the first layer is called the topsoil the second layer is called the bedrock and the layer that holds water is called doldrums

the bottom layer of soil is broken-down bedrock. first one is topsoil. second one is subsoil.
== == This layer is called bedrock.
The C horizon is based on bedrock. No soil is present that means that it is a layer of no penetration and usually consists of solid rock foundation.
