Corrasion
For a long time, Corrasion has been a topic of interest and debate in society. Since its inception, it has aroused the curiosity and reflection of various people around the world. Over the years, Corrasion has evolved and taken on different meanings and approaches, becoming a topic that encompasses a wide spectrum of ideas and opinions. From the academic field to the social field, Corrasion has been the subject of study and research, generating a great impact on the way we understand and approach various aspects of life. In this article, we will explore some of the perspectives and approaches that have developed around Corrasion, as well as its relevance in today's society.
Corrasion is a geomorphological term for the process of mechanical erosion of the earth's surface caused when materials are transported across it by running water, waves, glaciers, wind or gravitational movement downslope.[1] An example is the wearing away of rock on a river or seabed by the impact or grinding action of particles moving with the water.[2] The resultant effect on the rock is called abrasion.
Corrasion is different from corrosion which is due to chemical and solvent action of water on soluble or partly soluble rocks when they come in contact.
Corrasion acts in two ways:
- Lateral corrasion : the sideways erosion which widens the river.
- Vertical corrasion: downward erosion which deepens the river valley.
Thus corrasion is a form of erosion.[3]
