In the 1880s, the Harvard geographer William Morris Davis (1850–1934) began formulating a Cycle of Erosion to explain the temporal development of landforms.
The periglacial cycle of erosion begins with a non-periglaciated landscape. Once-periglaciated mass wasting of regolith exposes bedrock in the upper slopes. These outcrops are then subject to frost weathering that makes slopes retreat forming extensive blockfields at the base of the bedrock areas.
Davis, 1900. The glacial cycle of erosion deals with mountainous regions and lacks an old stage since Davis argues that nothing more developed than mature glacial landscapes exists at present. A glacial cycle of erosion begins with a pre-glacial landscape.
There had been some ideas on cyclical erosion in the Graeco-Roman world and then in the Islamic world and Europe during the Middle Ages. However the immediate influences of William Morris Davis, the creator of the cycle of erosion model, were 19th century American explorers.
Who discovered cycle of erosion?
geomorphic cycle, also called geographic cycle, or cycle of erosion, theory of the evolution of landforms. In this theory, first set forth by William M. Davis between 1884 and 1934, landforms were assumed to change through time from “youth” to “maturity” to “old age,” each stage having specific characteristics.
Who first postulated the idea of fluvial cycle of erosion?
The cycle of erosion was a model for stream erosion and landscape development proposed by William Morris Davis in the late 19th century.
Who introduced the non cyclic concept of landform evolution?
Cyclic concept was probably postulated first in geology by Scottish geologist James Hutton in 1785 when he propounded the concept of ’cyclic nature of the earth history’ and the dictum of ’no vestige of a beginning; no prospect of an end’ and ’present is key to the past’.
What is cycle of erosion according to Davis?
geomorphic cycle, also called geographic cycle, or cycle of erosion, theory of the evolution of landforms. In this theory, first set forth by William M. Davis between 1884 and 1934, landforms were assumed to change through time from “youth” to “maturity” to “old age,” each stage having specific characteristics.
What is Davis theory?
Davis developed a theory of landform creation and erosion, which he called the “geographical cycle.” This theory is more commonly known as the “cycle of erosion,” or more properly, the “geomorphic cycle.” His theory explained that mountains and landforms are created, mature, and then become old.
Who proposed the erosion cycle theory?
The Cycle of Erosion formulated by the American geographer William Morris Davis in the 1880s remained the dominant paradigm in geomorphology well into the 20th century, before it waned in response to improved understanding of Earth’s crustal and surface behavior.
What is the initial landform of Davis cycle of erosion called?
The initial, or youthful, stage of landform development began with an uplift that produced fold or block mountains. Upon dissection by streams, the area would reach maturity and, ultimately, would be reduced to an old-age surface called a peneplain, with an elevation near sea level.
What is Davis cycle of erosion?

Davis between 1884 and 1934, landforms were assumed to change through time from “youth” to “maturity” to “old age,” each stage having specific characteristics.
What are the three stage of Davis erosion cycle theory?
In a normal cycle three stages have been recognized as: youth stage, mature stage and old stage. These follow each other in a regular sequence. In this stage the river flows along an uneven surface and there is intensive bottom erosion, the gradients are steep and the erosion is rapid.

Davis developed a theory of landform creation and erosion, which he called the “geographical cycle.” This theory is more commonly known as the “cycle of erosion,” or more properly, the “geomorphic cycle.” His theory explained that mountains and landforms are created, mature, and then become old.
What is the difference between WM Davis and Penck’s cycle of erosion?
Davis Geographical Cycle of Erosion is a monocycle that means a cycle complete after the old stage of landforms whereas the Penck erosion cycle is polycyclic which means a never-ending process, the cycle starts again with the rejuvenation of landforms.
