Davis, 1900: Le cycle glaciaire de l'érosion concerne les régions montagneuses et n'a pas de stade ancien puisque Davis soutient que rien de plus développé que les paysages glaciaires matures n'existe actuellement.

The theory of the cycle of erosion put forward by W.M. Davis has been criticized by many geographers because of the following reasons: W. Penck does not accept the three stages of the cycle of erosion viz., the youth stage, the mature, and the old stage. In the opinion of several German Geologists, Now erosion starts and the whole cycle passes through the following three stages: (1) Youthful stage: Erosion starts after the com­pletion of the upliftment of the landmass. The top- surfaces or the (2) Mature stage: The early mature stage is heralded by marked lateral erosion and well integrated Cycle of Erosion by Davis – Assumption | Theory | Criticism A brief history of the theory postulated by Davis. In 1859, famous book of Charles Darwin ‘On the Origin of Species by Assumptions. To develop his theory ‘Geographical Cycle of Erosion’, Davis mentioned some basic assumptions.
