This hypothetic sequence of soil development is known as a Ultisol Lithosequence with the likely progression of Andisol, Vertisol, Histosol soil orders.
As the weathering of the rocks depends upon its erodibility of the base rock as the rock from the bottom are strong or resistant to corrosion caused due to the water and winds the rock masses above are stable.
This phenomenon is considered of paramount significance in desert climatic regions and the coat regions of the world. With respects to the shaking of the ground at the time of earthquakes or volcanic eruptions.
the base becomes significant as the weaker zones that are much prone to earthquakes or the rocks that are shallower or far become the dominant factors to the damages.
Weaker sections of rocks are found near the volcanic and mountainous zones. Like diamond is the hardest trick exist on earth and hence does get destroyed easily.
