Region of StudyNW Europe & Northeast USASlopes of Andes & AlpsSlopes of South Africa
ClimateHumid areasTectonic AreasSemi-arid landscape; sea cliffs with wave-cut platform
Description of SlopeInitially has steepest slope & with time angle decreasesReduction in maximum angle as gentler lower slopes erode backMaximum angle remains constant like slope facets apart from lower ones which increases concavity

ProcessBy stage 4, land turns convex-concave slopeScree slope B will replace slope A; slope C replaces slope BFlash floods remove concave debris on slope pediment
Changes over TimeIntermediate denudation assumes rapid land uplift.Starts with straight rock slope with equal weathering overall.Considering two facets of slope viz. , gentle concave lower slope, & convex upper slope.
