2) that many geomorphic systems are best understood in terms of the stochasticity of the processes occurring in them, that is, the probability distributions of event magnitudes and return times. [ 42 ] [ 43 ] This in turn has indicated the importance of chaotic determinism to landscapes, and that landscape properties are best considered ...
Desert geomorphology or the geomorphology of arid and semi-arid lands shares many landforms and processes with more humid regions. One distinctive feature is the sparse or lacking vegetation cover, which influences fluvial and slope processes, related to wind and salt activity. [4]
Bioerosion is the weathering and removal of abiotic material via organic processes. [10] This can either be passive or active. Moreover, bioerosion is the chemical and or the mechanical weathering of landforms due to organic means. [3] Bioprotection is essentially the effect that organisms have on reducing the action of geomorphic processes.
While surprising given the centuries of observation of fluvial and pluvial erosion, this is more understandable given early geomorphology was largely developed in Britain, where the effects of coastal erosion are more evident and play a larger role in geomorphic processes. [9] There was more evidence against marine planation than there was for it.
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system.. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin.
Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1] Folding , faulting , volcanic activity , igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. [ 2 ]
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 primary processes are mass wasting and the freeze and thaw cycle, [1] in which fallen snow gets compacted into firn or névé. The importance of the processes covered by the term nivation with regard to the development of periglacial landscapes has been questioned by scholars, and the use of the term is discouraged. [2]
