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 .
Lagoon – Shallow body of water separated from a larger one by a narrow landform; Lake – Large inland body of relatively still water; Lava lake – Molten lava contained in a volcanic crater; Maar – Low-relief volcanic crater; Nivation hollow – Geomorphic processes associated with snow patches
Topography can modify the local climate, for example through orographic precipitation, which in turn modifies the topography by changing the hydrologic regime in which it evolves. Many geomorphologists are particularly interested in the potential for feedbacks between climate and tectonics, mediated by geomorphic processes. [4]
Hydrogeomorphology has been defined as “an interdisciplinary science that focuses on the interaction and linkage of hydrologic processes with landforms or earth materials and the interaction of geomorphic processes with surface and subsurface water in temporal and spatial dimensions.” [1] The term 'hydro-geomorphology’ designates the study of landforms caused by the action of water.

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.
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]
They split a rock body into long, prisms or columns that are typically hexagonal, although 3-, 4-, 5- and 7-sided columns are relatively common. They form as a result of a cooling front that moves from some surface, either the exposed surface of a lava lake or flood basalt flow or the sides of a tabular igneous intrusion into either lava of the ...
Despite this, azonal processes and landforms might still take on particular characteristics when developing under the influence of particular climates. [3] When identified, morphoclimatic zones do usually lack sharp boundaries and tend to grade from one type to another resulting in that only the core of the zone has all expected attributes.
