During studies on land relief dynamics, we learned that the Earth's surface layer is continuously undergoing transformations, caused by some elements, such as wind and water, which are called exogenous agents of relief. Thus, we learned that these elements act in Law Suit of weathering and erosion on the rock formations and soils that make up the terrestrial morphology.
But after all, what is the difference between weathering and erosion?
Although many people believe that these are the same or synonymous procedures, weathering and erosion are different concepts. Using one concept in place of the other can be terribly misleading, so the two cannot be confused. Check out the differences:
The concept of weathering – also called weathering – refers to the set of chemical, physical and biological processes responsible for the disaggregation (breaking) or decomposition of rocks. It is through weathering that sediments (rock particles) are formed, as well as soils, which are exactly made up of decomposed and disaggregated rocks.
The concept of erosion, on the other hand, designates the set of stages that bring together the wear, transport and deposition of sedimentary material, that is, of rock and soil particles.
In short, we can say that erosion is the process of transport of particles of rocks decomposed or disaggregated by weathering. These are occurrences, therefore, interconnected and that act together in the dynamics of transformation of the relief.
Both weathering and erosion are early participants in the formation of sedimentary rocks, since the sediments generated by weathering and transported by erosion, after undergoing a series of transformations, become sedimentary rocks and sedimentary basins.
