In hydrology, capillary action describes the attraction of water molecules to soil particles. Capillary action is responsible for moving groundwater from wet areas of the soil to dry areas. Differences in soil potential ( Ï m {\displaystyle \Psi _{m}} ) drive capillary action in soil.
Soil scientists call it a soil profile. Topsoil, subsoil, and parent material are the three major layers found in most soil profiles. The layers can be as thin as a dime or several feet thick. The bottom layer is the parent material from which the soil is formed. The middle layer is the subsoil, and plants donât grow well in it. The top layer is the topsoil. Most life is found in the topsoil, and plants thrive in it. Topsoil is the most fragile layer because it is exposed to wind and water erosion and misuse. A Typical Soil Profile. Each soilâs profile determines how that soil will respond to our use of it.
