It is suggested that the evolution of morphology on a hard rock surface should be studied at a micro-scale. At this scale there is a reasonable chance of establishing the relationship between the operation of process events and the progression of erosion rates. Micro-erosion meters and micro-weighed weight-loss tablets make this possible. However, …
