In this soil profile activity, students are given a diagram of the layers in soil and answer questions about each layer and the processes involved in forming the soil profile. The greatest degree of weathering is in the top layer. The C-horizon lacks the properties of O, A and B- horizons because it is influenced less by the soil-forming processes. Soil layer scheme with grass and roots, earth texture and stones. These layers or horizons are known as the soil profile.
