Explanation:

There are 3 relative stages of soil development, young, mature and old.The young stage is characterised by the dormant control of the parent material and invading organisms. The soils of the young stage evolve from recently deposited river alluvium and glacial till. They are poorly developed and do not have the characteristic horizons.The mature stage reflects a greater influence of climate and these soils are developed over a long period of time. It has a well-developed profile of horizons which remains constant through time.The old soils mostly occur in the tropical regions and are one to six million years in age.
