    Soil with particle size in between 4.75 mm to 0.075 mm is called Sand. The sand is sub-divided as Coarse Sand (4.75 mm to 2.0 mm) Medium Sand (2.0 mm to 0.425 mm) and Fine Sand (0.425 mm to 0.075 mm). Soil with particle size less than 0.075 mm is called Fine-Grained soil (Silt or Clay) and soil with particle size in between 80 mm to 0.075 mm
