(ii) Losses of mineral and organic matter from soil. tarhab asgharWebA fourth factor of soil formation is the configuration of the landscape; i.e., the topography of the area in which the soil develops. Topography affects soil formation in various ways. Where the land is flat, the processes of energy exchange and of water inflow and release tend to be vertical, so the soil develops to a characteristic depth. 類語 念のため
