Final answer:
Rock type affects cliff profiles through erosion resistance and rock composition.
Step-by-step explanation:
Rock type can have a significant effect on cliff profiles. Different rock types have varying degrees of resistance to erosion, which can result in different shapes and features of cliffs. For example, harder rock types like granite are more resistant to erosion and may form steep cliff faces, while softer rock types like shale are more easily eroded and may result in gentle sloping profiles.
Additionally, the composition of rock can also impact cliff profiles. For instance, sedimentary rocks like sandstone often exhibit cross-bedding, which is visible as inclined layers within the rock. This can create distinctive patterns and features on cliff faces.
In summary, rock type can affect cliff profiles through its resistance to erosion and the composition of the rock.
