Question

state two feature of middle course of river​

Answer 1

Answer:

As the river erodes laterally, to the right side then the left side, it forms large bends, and then horseshoe-like loops called meanders.

The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.

The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction.

On the inside of the bend, where the river flow is slower, material is deposited, as there is more friction.

Answer 2

The middle course of river has two main features:

(i) Meanders and (ii) Ox-bow lakes. These are both results of varying speeds and friction levels in the faster moving water, as compared to the upper course.
