E. Think and answer.
1. Why is the speed of the rivers fast in the mountains and slow at the mouths?
2. Why does the River Ganga slow down before joining the Bay of Bengal?​

Answer 1

Answer:

but at the mouth, the terrain is flat. so water flow is low. The speed of the river is fast in the mountain because in mountainous region the river experiences its youth stage. ... The sediments get collected on the river bed and the water gets heavy ultimately resulting into a slow and steady water flow
