Hill Slopes

Various theories have been proposed to describe the mechanisms of slope development, each offering a unique perspective on how slopes transform. From W.M. Davis’ concept of slope decline, which emphasizes a gradual reduction in slope steepness, to W. Penck’s slope replacement model, which focuses on the accumulation of debris at the base, these theories highlight…

This angular inclination of terrain between hilltops and valley bottoms is what we call a slope. But why does this happen? What shapes these…
