Answer :

Gradation is the process of levelling up and formation of land surface by the operation of natural agents like air, water, glaciers or sea waves. Running water and rives are very important agents of gradation. The extent of the action of rivers depends upon many factors. The volume of water in the river, its velocity and speed, the gradient and slope of the land, the number of sediments and particles carried by the river are some of the factors determining the flow of the river.
