Question

classify the soils? Explain​

Answer 1

Answer:

According to the USCS classification, soil is divided into: coarse grained soil, fine-grained soil, and highly organic soil. The particle size distribution of soil and consistency limits are used in classification of soils. ... The exceptions are cases when the soil is marked with double symbols consisting of four letters.Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay. ... Silty soil contains particles, which are smaller than sand particles but larger than clay particles.They also include bits of decayed animals and plants. Soil also contains water and air. There are three different types of soil—sand, silt, and clay. Each type of soil has different characteristics.All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour.
