Davis found a few significant differences between the cycle in arid regions and humid regions, viz., differences in the manner of runoff, maximum relief in youth rather than in mature stage, relief decreasing as the cycle progressed, consequent drainage flowing into enclosed basins with few antecedent streams, highlands actively dissected in youth and basin aggradation, lack of continuous
Only Ias Exam. W M Davis was an American geographer. He gave the cycle of erosion in 1899 based on the erosion pattern of American mountainous Valleys. As per Davis, in the beginning, there was a flat surface and due to endogenic force sudden landmass uplifted then the process of landform development started.

His ‘geographical cycle’ has been defined in the following manner: Davis conceived the cycle of erosion model in the 1880s. More fully developed by 1900 it received wide acclaim, but was never universally accepted. The initial enthusiasm and strength of the cycle of erosion model has been attributed to various causes. The originator of the erosion cycle model, William Morris Davis, divided it into stages.

The main points of his theory are as under: A cycle of erosion would affect all landscapes. In 1859, famous book of Charles Darwin ‘On the Origin of Species by Means of Natural Selection’ was published. That was based on the theme of change or evolution of living species over time. Being highly influenced by Darwin’s theory, in 1884, William Morris Davis first formulated the concept of geomorphic cycle, and this theory was published in the International Geographical Congress in 1889, entitled as ‘Theory of Cycle of Erosion’.

Comparison between Davis and Penck model of geographic cycle • According to Davis , upliftment finished before degradation starts where as Penck said upliftment and degradation starts together as soon as the landmass come above the sea level.
He also put forward a theory of the cycle of erosion. The main points of his theory are as under: A cycle of erosion would affect all landscapes. In 1859, famous book of Charles Darwin ‘On the Origin of Species by Means of Natural Selection’ was published. That was based on the theme of change or evolution of living species over time. Being highly influenced by Darwin’s theory, in 1884, William Morris Davis first formulated the concept of geomorphic cycle, and this theory was published in the International Geographical Congress in 1889, entitled as ‘Theory of Cycle of Erosion’. Various models were developed on the basis of this reference system e.g., normal cycle of erosion, arid cycle of erosion, glacial cycle of erosion, marine cycle of erosion etc.

Davis (1902) also introduced the concept of a graded stream, where erosion and highways to migrate and spawn in regular cycles tied to rainfall and seasons. According to Davis, the cycle of erosion describes landform as the work of structure, process and time. Penck proposes formation of landforms as the result of rate. 28 Dec 2019 The extended depression on the ground through which a stream flows is called a river valley.
