‘NORMAL CYCLE OF EROSION’

The normal cycle of erosion is mainly formed due to land rises and the upliftment process of landmass mainly found in the progressive river valley regions. The erosion is mainly characterized by successive development of landmasses, especially in the river basin and the mountainside. The transformation of the normal cycle of erosion has developed into three significant stages such as youth, mature, and old stages. Crustal stability in the landmasses witnesses the upliftment of landmasses in the subside of different land areas, particularly in the mountainside and river basin region. Because of endogenic forces, the consequent streams create several rills as well as gullies that cause the normal cycle of erosion.

A normal cycle of erosion: overview

The continuous erosion cycle creates a greater transformation in the landmasses of world physiography and forms a narrow and deep landform in the mountainside and river basin area. The gorges and canyons in the river basin are transformed into a different landmass because of a normal cycle of erosion. 

A cycle of erosion: definition 

A cycle of erosion is an idealized model, which refers to the relief landscape development with the formation of the base level of river and landmass upliftment. Peneplain formation and incision of riverside regions witness the most cycle of erosion that forms slope declination in different areas. Apart from that, the peneplain consists of different high stands that cause a next level erosion cycle with an initial steep slope.

A normal cycle of erosion: definition

From the landscape perspective, the cycle of erosion is widespread in different areas, especially by the riverside and the mountainside as this area consists of different types of landmasses, soft and hard. Developing weathering relief and the levels of erosion make the landmasses plainer and the landscape evolution is mainly found in the initial stage of river formation and due to high water flow in the mountain region so most of the cycle of erosion is found in that particular area.

Stages of the normal cycle of erosion

• Youth stage of a cycle of erosion: The erosion cycle mainly starts in this stage after the upliftment of landmass compilation. In this stage, the uppermost surface of the landmasses forms an erosion cycle as several small and big rivers flow in that region. The Big Rivers with their tributaries engaged a hard formation of the cycle of erosion lengthening. This stage is characterized by the increasing rate of vertical erosion that depends on the landmass character.

• The mature stage of a cycle of erosion: This stage is characterized by integrated drainage systems of different landforms and heralded with the help of lateral erosion. In this stage, the vertical erosion level is reduced considerably and the speed and flow of the river are decreased in this stage due to plain landforms. Apart from that, the absolute relief along with relative relief of the cycle of erosion is also reduced considerably.

• Old stage of a cycle of erosion: The old stage of the cycle of erosion mainly dorms a different type of landmass with the soil that has been ruined in the previous two stages of the cycle of erosion. This stage of the cycle of erosion is characterized by the absence of erosion level and thus the valleys of a mountain it river widened with the incision of lateral erosion.

Conclusion 

A cycle of erosion is mainly dependent on the flow of the river and the characteristics of the landmasses as the landforms vary from different regions. Relative relief along with absolute relief reduces sharply in the last stage to erosion the tributaries of the river especially in the mountain area with high and low landforms are a great cause of erosion and improve drainage patterns with a high velocity of water flow. A high flow rate and vertical channel erosion make the landmass soft and ideal for the normal cycle of erosion.
