Q. With reference to the landforms formed due to running water, which of the following statements is/are correct?
1. There are no depositional forms associated with streams flowing over steep slopes.
2. The vigorous the river channels in gradient, the greater is the deposition.
Select the correct answer using the codes given below:

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: D
Notes:

There are two components of running water. One is overland flow on general land surface as a sheet. Another is linear flow as streams and rivers in valleys.  

  • Most of the erosional landforms made by running water are associated with vigorous and youthful rivers flowing over steep gradients.  
  • With time, stream channels over steep gradients turn gentler due to continued erosion, and as a consequence, lose their velocity, facilitating active deposition.  
  • There may be depositional forms associated with streams flowing over steep slopes. But these phenomena will be on a small scale compared to those associated with rivers flowing over medium to gentle slopes.  
  • The gentler the river channels in gradient or slope, the greater is the deposition.
