layer of soil are topsoil,subsoil,bedrock

Answer 2

1. Soils develop in parent material from the time of its deposition under the influence of local climate, topography, and biota.

2. The process of soil development is often refered to as soil weathering. Over time, a number of environmental forces act to create distinct layers or horizons parallel to the soil surface.

3. This occurs through the differential downward movement of materials, such as organic matter or clay particles.

4. The movement and accumulation of materials at depth affects soil texture, structure, and/or color.

5. These are three properties that are useful for distinguishing horizons. For example, accumulation of clay affects texture and structure and an accumulation of organic matter affects color.

6. However, these are not the only soil properties used to distinguish horizons.

7.For example, the depth to parent material in a calcareous till is best determined by testing for the presence of carbonates.
