A soil profile is a vertical cross section of soil that shows the different layers or horizons of soil from the surface to the deepest extent of plant root activity or to the regolith and bedrock. A pedon is a small unit of soil that can be observed and studied in its natural state, while a soil horizon is a distinct layer or zone within a soil profile. A polypedon is a group of pedons, and regolith refers to the layer of loose material covering solid rock.
