Organisms affect geomorphic processes in a variety of ways. For example, trees can reduce landslide potential where their roots penetrate to underlying rock, plants and their litter inhibit soil erosion, biochemicals produced by plants accelerate the chemical weathering of bedrock and regolith, and marine animals cause the bioerosion of coral.
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]
Nivation hollow – Geomorphic processes associated with snow patches; Oxbow lake – U-shaped lake or pool left by an ancient river meander; Panhole – Depression or basin eroded into flat or gently sloping cohesive rock; Pothole – Natural bowl-shaped hollow carved into a streambed; Plunge pool – Depression at the base of a waterfall
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 ...
Periglacial processes—those that directly involve ice—may be prominent in the early stages of paraglacial landscape response, but the two terms are not synonymous. Many geomorphic processes that don't require freezing conditions—for example fluvial erosion, transport and deposition—are typically involved in paraglacial change.
Example of a periglacial landscape with both pingos and polygon wedge ice near Tuktoyaktuk, Northwest Territories, Canada. Periglaciation (adjective: "periglacial", referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost. The meltwater ...
Geomorphology (from the Greek words Ge = earth, morfe = form and logos = study) is the science of surface features and landforms including the forces and processes that create them. Geomorphology has strong ties to geologic structure, rock types, and local/regional climate.
Denudation can involve the removal of both solid particles and dissolved material. These include sub-processes of cryofracture, insolation weathering, slaking, salt weathering, bioturbation, and anthropogenic impacts. [4] Factors affecting denudation include: Anthropogenic (human) activity, including agriculture, damming, mining, and ...
