Question

With reference to the development of a River Valley consider the following statements and choose the correct one.

In the upper course of a river, there is the maximum gradient of the slope. In this part, the river has maximum erosive capacity. There is more down cutting than lateral cutting.

In the middle course the erosion and the deposition capacity of the river are almost equal. In this part, the river flows relatively with mild velocity.

In the lower course, the river runs at a slow speed or is slow-paced. Its chief work is deposition.

Select the correct answer using the codes given below:

Options:

A . 1 and 3

B . 1 only

C . 1, 2 and 3

D . 2 and 3

Answer: Option C
Answer: (c)
In the upper course, there are features of the youthful stage. The landforms of erosion include deep valleys, gorges, canyon, waterfalls, rapids.
Interlocking spurs etc. In the middle course, the landforms like alluvial fans, meanders and ox-bow lakes are formed. In the lower course landforms found include flood plains, natural levees, delta etc. which are all landforms of deposition and show old age.
