Gradation is the process of removing unevenness of the land surface and making it a level land. Agents of gradation are running water, wind, glacier, waves, and underground water. Gradation can be of two types- degradation and aggradation. • Degradation is the process of denudation.
What are the three kinds of gradational processes?
There are three processes of gradation, they are weathering, transport, and deposition. Weathering is a general process by which rocks break down and wear away at the Earth’s surface.
Is folding a gradational process?
These tectonic forces included vulcanism, faulting, and folding, all produced by plate tectonic forces. Collectively, these forces are called “gradation,” and they comprise fluvial (flowing water), glacial (moving ice), coastal (waves), and æolian (wind) processes, together with weathering and mass wasting.
What is known as gradation?
noun. any process or change taking place through a series of stages, by degrees, or in a gradual manner. a stage, degree, or grade in such a series. the passing of one tint or shade of color to another, or one surface to another, by very small degrees, as in painting or sculpture. the act of grading.
What is the process of gradation Upsc?
The actions of exogenic forces result in wearing down (degradation) of relief/elevations and filling up (aggradation) of basins/ depressions, on the earth’s surface. The phenomenon of wearing down of relief variations of the surface of the earth through erosion is known as gradation.
Why erosion is gradational process?
Gradational processes Weathering = breakdown of material in place Gradation = leveling of land degradation (erosion) = removal of highs transportation = movement of material aggradation (deposition) = filling in lows Tectonic processes build up of roughen up the earth Gradational forces level off highs and fill in lows
What is gradational force?
Gradational forces are those exogenetic forces on the surface of the earth which are responsible for the denudation in a gradational manner or in a which include the process of weathering and erosion.
What are geomorphic processes?
The geomorphic process means bringing about changes in the configuration of the Earths surface, due to physical stresses and chemical actions on materials present on earth. The physical and chemical action are due to endogenic and exogenic forces.
What do gradational forces do?
weathering and erosion by wind, water and ice. These forces change or modify those landforms made by tectonic forces.
What is geomorphic agent Upsc?
What are the Geomorphic Agents? A geomorphic agent is a mobile medium which removes, transports and deposits earth materials. The examples of geomorphic agents are running water, glaciers, wind, waves, ocean currents, groundwater etc.
What is aggradation and degradation?
Aggradation refers to an increase in elevation of land usually in river system due to deposition of sediments. Degradation occurs due to erosional activities of mainly wind and water. It refers to the lowering of a landform through erosional process.
What are the two types of gradational process?
Gradation can be of two types- degradation and aggradation.
What is gradation and examples?
The definition of a gradation is a process of arranging in a series of stages or one step in the process. An example of gradation is the movement through the various grades of school. An example of gradation is the 5th grade in the grand scheme of schooling. noun.
What is Epeirogenic process?
Epeirogenic processes involving uplift or warping of large parts of the earth’s crust, thus it is a continental building process. They act along the earth’s radius and thus are also called radial movements. When direction of movements is towards, it is subsidence.
What are the 5 geomorphic processes?

What are the 4 Exogenic processes?
Weathering, mass wasting, erosion, and deposition are the main exogenic processes. All the exogenic processes are covered under a general term- denudation, which means strip off or uncovers. The elements of nature capable of doing these exogenic processes are termed geomorphic agents (or exogenic geomorphic agents).
