The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. [1] The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. [1]

The cycle of erosion by fluvial processes (run­ning waters or rivers) is called normal cycle of erosion because of the fact that fluvial processes are most widespread (covering most parts of the globe) and most significant geomorphic agent.

Davis has described his model of geographical cycle through a graph below (fig. 16.1): The cycle of erosion begins with the upliftment of landmass. There is a rapid rate of short-period upliftment of landmass of homogeneous structure.

Feb 23, 2024 · The geomorphic cycle, also known as the geographic cycle, is a theoretical framework used to explain the long-term evolution of landforms. It describes the continuous process of erosion, transportation, and deposition that shapes the Earth’s surface over time.

Jan 27, 2025 · erosion, removal of surface material from Earth’s crust, primarily soil and rock debris, and the transportation of the eroded materials by natural agencies (such as water or wind) from the point of removal.

Mar 14, 2025 · Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Cycle of Erosion (Davis) 1.1 Introduction James Hutton 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 the key of past’. The concept of cyclic nature of the earth history was later on transferred into the concept of

The cycle of erosion, as envisioned by Davis, has its initial stage at a time when the landmass is rapidly elevated by internal earth forces, followed by a very long period of tectonic quies¬cence.

WM Davis was an American geographer. He gave the concept of a "geographical cycle" known as an "erosion cycle" in 1899. Davis studied the Appalachian Mountains of North America, which is a humid climatic region, and based on the study, he proposed the cycle of erosion.

Walter Penck gave a geomorphological system model in 1924 also known as the cycle of erosion. According to Penk, Erosion of landforms starts with the start of the upliftment process. Upliftment and erosion processes go simultaneously.
