Answer:
1)A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D.
2)Soil Horizons (layers): Soil is made up of distinct horizontal layers; these layers are called horizons. They range from rich, organic upper layers (humus and topsoil) to underlying rocky layers ( subsoil, regolith and bedrock).
3)The main rock particles present in the top-soil are sand, clay and silt. So, depending on its composition, a soil can be classified as sandy soil, clayey soil or loamy soil. All these soils have different proportions of rock particles of different sizes.
4)Loamy soil is the mixture of sandy soil, clayey soil and silt. Silt is the deposit in river beds. Loamy soil has right water holding capacity and is well aerated. This is considered as the best soil for the growth of plants.
5) Clay soil
The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. Conversely, sands provide easier passage or transmission of water through the profile.
