WebRotational downwards movement of incompetent rock and material. Natural factors that can cause landslips and slumping: Rock type - Strong competent rocks are less likely to fail than weak, incompetent rocks. Strong competent are more likely to fails by slipping and incompetent rocks are more likely to slump. Competent rocks are more commonly exposed at outcrops as they tend to form upland areas and high cliffs, or headlands where present on a coastline. Incompetent rocks tend to form lowlands and are often poorly exposed at the surface. During deformation competent beds tend to deform elastically by either buckling or faulting and fracturing. Incompetent beds tend to deform more plastically, although it is the competence contrast between different rocks that is most importan…
