A soil profile consists of
Solution. The soil profile is the layers of soil found when we go deeper into the ground. There are three main layers of soil – top soil, subsoil and parent rock. Topsoil ( A – horizon): Top soil is the upper most layer of the soil which is made up of humus and small particles of rocks. It is dark in colour due to the presence of humus.A soil profile consists of 10 m of gravel overly ing a clay lay er of 3 m . thickness, which in turn r ests on a 3 m sa nd lay er. The draine d and saturated unit . A soil profile consists of a clay layer and two sand layers; the clay layer is “sandwiched” between two sand layers as shown below. A surcharge of q = 120 kN/m2 is applied to the ground surface, which causes an increase of total stress (Δσ) of approximately 120 kN/m2 in the clay layer from top to bottom.

Soil consists of organic matter (about 5%), inorganic mineral matter (40-45% of soil volume), water (about 25%) and air (about 25%) (Figure 2.3.2 2.3. 2 ). The amount of each of the four major components of soil depends on the amount of vegetation, soil compaction, and water present in the soil.These layers are called soil horizons/layers and the arrangement of these horizons in soil or the vertical section of the soil is known as a soil profile. A soil pit is a place where the secrets of the soil are hidden. You can also say it is the sequence of layers.
