Geomorphologic Explanation of Erosion Concept and Comparing it to Natural Resources Science Aspects

Erosion means the harvesting، transportation and movement of eroded material. The concept is very extensive erosion that has different definitions in different disciplines. The purposes of this paper is finding a brief definition of “erosion” concept in different perspectives and comparing it in Geomorphologic and Natural Resources point of views. To achieve this goal، we try to use the library documents، analyze and compare the findings of this work with each other. Results show that most differences between these approaches، different time، place، is corrosive agents and erosion processes. In Geomorphologists view of point،erosion is a natural phenomenon and Sformation of it is slow and makes landscapes and landforms that are environmental resources suitable for human life. But the erosion in the point of Natural Resources Science view is destruction of fertile soils and have negative effects on the lives of many inhabitants of the plan. Natural Resources Science specialists believe that soil erosion phenomena even is a destructive force for civilizations. General concept of erosion according to the type and scope of the study has significant differences from the perspective of Natural Resources Science and Geomorphology.
