WebLithology concerns the physical properties of a rock.For example, the lithology of the coast affects the speed at which it erodes or recedes. Cliffs made of hard rocks are more resistant to weathering and erosion, and they will change very slowly. Soft rocks, on the other hand, are more susceptible to weathering and erosion and will change relatively quickly. Webchanges abruptly at the lithology boundaries as shown.
