The very first step of soil formation begins with the bottom-most layer which consists of parent material or bare rock. This rock breaks down over time to form the next layer which is the weathered parent material layer. This consists of broken down rock through natural processes such as rain, wind, floods, and even lichens which are organisms that secrete acid onto bare rock and break it down over time (Withgott & Laposata, 2015, p. 77). The following layer is the leaching layer and this is the layer where water and nutrients flow through with ease, escaping from the upper layers of the soil.
