Question
Erosional work of rivers
✓
Answer
The rivers originate at a much higher altitude from the sea level.
Here, the river flows at a great speed and therefore, its power to erode is great.
The riverbed and the river banks get eroded because of the speedy flow of the river, sand particles, pebbles. Also, various tributaries join the main river.
All these lead to the formation of gorges (canyons), V-shaped valleys and waterfalls.
