Erosion is a dynamic process. Forces such as river, sea waves, winds, glaciers and underground water which participate in the process of erosion are known as components of erosion. It is not essential that all these components participate in the process of erosion in an equal measure or at an equal rate, because the climatic condition of a particular region influences the structure and composition of rocks. If these components of erosion were not present, then the surface would always be dissimilar which would be an undesirable condition.
