Question

Why does the river start meandering in the middle course

Answer 1

As the river makes its way to the middle course , it gains more water and therefore more energy, so material can be carried in suspension and is used to erode the river banks. Lateral erosion starts to widen the river. When a river flows over flatter land it develops large bends called meanders .

Answer 2

A meander is a winding curve or bend in a river. They are typically found in the middle and lower course of a river.

Step-by-step explanation:

This is because vertical erosion is replaced by a sideways form of erosion called lateral erosion, plus deposition within the floodplain.
