The model in its original form is intended to explain relief development in temperate landscapes in which erosion by running water is assumed to be of prime importance. [ 5 ] [ 7 ] Nevertheless, the cycle of erosion has been extended, with modifications, into arid , semi-arid , savanah , selva , glacial , coastal , karst and periglacial areas.

This conical hill in Salar de Arizaro, Salta, Argentina called Cono de Arita constitutes a landform. A landform is a natural or anthropogenic [1] [2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography.
Rainfall and snowfall increase on the mountains as these rise, perhaps at a rate of a few millimeters per year (at a growth rate of 1 mm/year, a 5,000 m tall mountain can form in 5 million years, a time period that is less than 10% of the life of a typical collision zone). River systems form, and glaciers may grow on the highest peaks.
The remains of such mining methods are very visible landform features in old goldfields such as in California and northern Spain. The badlands at Las Medulas , for example, was created during the Roman period by hushing or hydraulic mining of the gold-rich alluvium with water supplied by numerous aqueducts tapping nearby rivers.

Traditionally in geomorphology, a flatiron is a steeply sloping triangular landform created by the differential erosion of a steeply dipping, erosion-resistant layer of rock overlying softer strata. Flatirons have wide bases that form the base of a steep, triangular facet that narrows upward into a point at its summit.
Each stage has distinct landforms and other properties associated with them, which can occur along the length of a river's upper, middle, and lower course. Though the cycle of erosion was a crucial early contribution to the development of geomorphology , many of Davis' theories regarding landscape evolution, sometimes termed 'Davisian ...
Within geomorphology a relict landform is a landform that took form from geomorphic processes that are not active at present. In a Scandinavian context, this is often meant to imply that relict landforms were formed before the last glaciation and survived it under cold-based parts of the ice sheet . [ 4 ]
