Rocks were slowly broken down to smaller and smaller pieces by physical weathering, and then decomposed by chemical weathering to form the parent material, which may be defined as the weathered material from which the soil was synthesized. The parent material was further decomposed by the action of [...]
After reading this article you will learn about the principle and pipette method of mechanical analysis of soil. Principles of Mechanical Analysis: It is based on Stokes' law, according to which when the size of the soil particles is decreased, their time of settling below a constant of about 10 cm increases. So the time t secs of setting of [...]
