Cyclicity and Fluidity of Soil Formation

It is shown that multilevel cycles of soil formation, defined by repeated changes in the amount of heat coming from the Sun to the Earth’s surface, create conditions for the multistage evolution of the soil cover in a certain direction. However, soil, with its plasticity due to stresses and deformations caused by various external and internal forces, exhibit processes of introduction and removal of soil material and pedoturbation that determine the flow of soils. This soil flow interrupts” the cycles of soil formation, rejuvenating the soil and slowing down the overall evolution of the soil cover or letting it go along an unpredictable path.
