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.
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 ...
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
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.
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]
Mass wasting is a general term for any process of erosion that is driven by gravity and in which the transported soil and rock is not entrained in a moving medium, such as water, wind, or ice. [2] The presence of water usually aids mass wasting, but the water is not abundant enough to be regarded as a transporting medium.
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 ...
'measure'), is the science and practice of measuring the characteristics of terrain, the shape of the surface of the Earth, and the effects of this surface form on human and natural geography. [1] It gathers various mathematical, statistical and image processing techniques that can be used to quantify morphological, hydrological, ecological and ...
