Factors Controlling Landform Development
Geomorphology is that the study of the Earth’s surface landforms.
This study deals with morphology, geomorphologic, forms, origins and ages. (Baker 1986) The findings of this analysis are both descriptive and quantitative. Geophysics seeks to explain how land forms have been formed and how the evolution of land forms has been documented over time.
The geophysics of any region or site is the results of interaction involving 3 primary factors- method, structure, and time.
All Earth’s surface area units put through various physical, chemical, and biological processes that operate at highly varied rates.
Geophysics relates to the several activities of natural surface and subterranean agents engaged in the removal of prior and formation of the latest landforms on the earth’s surface.
- Landform area unit physical configurations of the Earth’s crust origin and evolution that shaped from natural processes like geological phenomenon, climate, erosion, and glaciation.
- Landforms are huge earth science options, like plains, plateaus, and mountains, or little ones like flood plains, hills, and sediment fans.
- Landform samples embody oceans, rivers, valleys, plateaus, mountains, plains, hills, and glaciers.
- A Landform is of the feature, like a slope, natural depression, or mountain.
- Landforms classified by their characteristics like physical features, location, height pitch, stratification, and composition.
- A landform scarcely any natural geographic feature that found on the surface of the earth, like valleys, mountains, hills, and tableland.
- Landforms classified by characteristic physical attributes like elevation, orientation, slope, stratification, soil sort, and rock exposure.
- Gross physical alternatives or types of land involve practical sections such as berm, valleys, mountains, mounds, cliffs, ponds, peninsulas, volcanoes, and numerous alternatives (e.g. reservoirs, hills, and mountains) as well as a range of midland and ocean waters bodies and sub-surface facilities. Nevertheless, alongside its encounters with alternate natural bodies such as geologists, the World Health Organization researchers have developed landforms.
Landforms created by several factors but all grouped into two main processes: Constructive and Destructive Processes.
This process includes the building (i.e., the addition of land material) of features either by natural action. The three main areas of constructive processes incorporates Crustal Deformation, Volcanic Eruptions, and Sediment Deposition.
Crustal Deformation: Example, Fold Mountains.
Volcanic Activity: Example, Plateau.
Sediment Deposition: Example, Coastline.
This involves the breakdown or tearing down of the land surface to form new features. This process may seen as ‘carving out’ parts of the land to form new features. The two main destructive forces that create and shape landforms are- weathering and Erosion.
Weathering and Erosion: Canyons, Islands and Valleys.
Meaning of ‘Controlling Factor’
(i) They do not involve in the creation or destruction of the landforms, but they identify the rate at which such destruction or deformation or formation will take place.
(ii) The controlling factors identify the magnitude, dimension, amplitude, shape, and size of the landforms.
