Soil forming processes a rather complex: they are depending on weathering processes, climate and land formation. The processes are highly depending on external factors:
- rock type (bedrock)
Each factor underlies also changes at different time levels and these changes consequently disturb the equilibrium. As result soils either erode and degrade or form new. Erosion, soil erosion and degradation is a relative quick process, whereas soil formation takes rather long. At a certain stage of degradation, soil formation is not possible anymore.
