Exfoliation contributes to the formation ofbornhardts, one of the most dramatic features in landscapes formed by weathering and erosion. The underlying rocks, released from overlying pressure, can then expand. A single type of weathered rock often produces infertile soil, while weathered materials from a collection of rocks is richer in mineral diversity and contributes to more fertile soil.
