Briefly describe the factors which affect the work of a river.
थोडक्यात उत्तर
उत्तर
Various factors affect erosion, transportation, and deposition work of a river. Important factors include the following :
- The velocity of water: Erosion and transportation are both maximum when velocity is high. Deposition, on the other hand, takes place when the velocity of water is low.
- The volume of water: The larger the volume of water, the greater is the power of erosion and transportation. Deposition, on the other hand, takes place better when there is a reduced volume of water as well as when the load is greater.
- Load: Load is the material transported by a river. A load of a river does all the work of erosion and deposition. Mass wasting, deepening of river valleys and formation of landforms depend on the load a river carries.
