Direction: Read the case study given below and answer any three of the questions that follow.
In humid regions, which receive heavy rainfall, running water is considered the most important of the geomorphic agents in bringing about the degradation of the land surface. There are two components of running water. One is overland flow on the 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. When the stream beds turn gentler due to continued erosion, downward cutting becomes less dominant and lateral erosion of banks increases and as a consequence the hills and valleys are reduced to plains.
Q. What happens when the stream beds turn gentler due to continued erosion?
- a)Floods occur.
- b)Hills and valleys are reduced to plains.
- c)New landforms are formed.
- d)Droughts are frequent.
Correct answer is option 'B'. Can you explain this answer?

Understanding Stream Bed Erosion
When stream beds turn gentler due to continued erosion, several geological processes occur that significantly alter the landscape.
Reduction of Hills and Valleys
- As streams and rivers flow over steep gradients, they primarily cut downward into the earth, creating deep valleys.
- Over time, as erosion progresses, the steep gradients become gentler. This shift leads to a decrease in the stream’s velocity, which changes the dynamics of erosion and deposition.
- With reduced downward cutting, lateral erosion of the riverbanks becomes more pronounced.
Formation of Plains
- The lateral erosion widens the river valley and flattens the surrounding terrain.
- As a result, the once prominent hills and valleys are gradually worn down and reduced in height and depth, leading to a more uniform landscape.
- This process ultimately transforms the area into plains, where the land becomes flatter and more level.
Consequences of Erosion
- The gentle slopes allow for increased deposition, where sediments carried by the stream settle on the riverbed and banks, further contributing to the formation of plains.
- This alteration in the landscape not only affects the physical geography but also can influence ecosystems and human activity in the region.
In conclusion, the transition of stream beds from steep to gentler gradients primarily results in the reduction of hills and valleys, leading to the formation of plains. This process highlights the dynamic nature of geomorphic agents like running water in shaping our landscapes over time.
