Climatic Geomorphology and Morphogenetic Regions

Geomorphology and climateGeomorphology- The scientific study of the formation, alteration, and configuration of landforms and their relationship with underlying structures. Climate- The composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years.

Climatic Geomorphology The relationship between landforms and climate is the basis

of a major philosophic approach in geomorphology known as climatic geomorphology

Geomorphic mechanisms vary in type and rate according to the particular climatic zone in which they function

Landforms produced from these mechanisms will be different from region to region and will reflect the dominant climate

Climatic GeomorphologyClimatic geomorphology can be defined as the discipline that identifies climatic factors such as the intensity, frequency and duration of precipitation, frost intensity, direction and power of wind, and it explains the development of landscapes under different climatic conditions.The concept of climatic geomorphology envisages that each climate type produces its own characteristics assemblages of landforms and set geomorphic process which set them.

Climatic GeomorphologyAccording to D. R. Stoddart (1969), the concept of geomorphology is based on some major themes-Landforms differ significantly in different climatic regionsSpatial variations of landforms in different climatic regions are because of spatial variations in climatic parameters (e.g. temperature, humidity, precipitation etc) and their influences on weathering, erosion and runoff.

Climatic GeomorphologyAccording to Climatic Geomorphology theory, the landforming processes are basically controlled bymean temperaturemean precipitation

Peltier’s Morphogenetic RegionsL. C. Peltier divided the world into 9 morphogenetic regions on the basis of two climatic parameters; they are mean annual temperature and mean annual rainfall.
