Which one of the following rivers is an example of superimposed river?

Correct option is C

The correct answer is (c) Banas.
Explanation:
· Superimposed Rivers: The Banas River is an example of a superimposed river in Rajasthan. Superimposed rivers are those that originally flow over a higher terrain but gradually cut down through erosion, superimposing their course onto the underlying rock structure.
· The Banas River flows through the Aravalli Range and has cut its way through the resistant rocks, following a course that was not determined by the underlying geology but rather by the overlying topography.
Important Key Points:
· Superimposed rivers provide insights into the geological history of a region, especially in terms of erosion and sedimentation processes.
· The Banas River, with its superimposed characteristics, is an important water source in Rajasthan, flowing through the Ajmer, Rajsamand, and Tonk districts.
· Rivers like the Banas play a crucial role in the hydrology of Rajasthan, providing water for agriculture, drinking, and other purposes in a largely arid state.
· The concept of superimposed rivers is important in geology and geography for understanding river dynamics and landscape evolution.
· The Banas River also supports a range of ecosystems along its course, contributing to the biodiversity of the region.
· The river is prone to seasonal fluctuations, with significant variations in flow between the monsoon and dry seasons.
Knowledge Booster:
· Ghaggar: Often considered the remnant of the ancient Sarasvati River, Ghaggar is an ephemeral river in the northwestern part of India.
· Mahi: A major river in western India, the Mahi is known for flowing through Gujarat and Rajasthan but is not a superimposed river.
· Jakham: Another important river in Rajasthan, it is a tributary of the Mahi River but does not exhibit superimposed characteristics.
