Which valley of the following rivers is known to deep Ravines ?

Question

UnlockIAS · Accepted Answer

Correct — C, Chambal. The Chambal valley, across the Morena–Bhind–Sheopur tract of northern Madhya Pradesh (and extending into adjoining Rajasthan and Uttar Pradesh), is famous for its badlands — deep, densely dissected ravines (locally called beehad) cut into soft alluvial soil by gully erosion. These 'Chambal ravines' are the classic Indian example of badland topography and historically sheltered dacoits.

Why the other options are wrong — (a) Wrong — the Narmada flows through a structural rift valley between the Vindhya and Satpura; it is not associated with ravine badlands.  (b) Wrong — the Son flows in a broad structural valley north-east of the Maikal; it has no notable ravine belt.  (d) Wrong — the Tapti occupies a rift valley south of the Satpura, parallel to the Narmada, and is not known for ravines.

Concept: Ravines (badlands) are a gully-erosion landform: running water carves a maze of deep, steep-sided channels into soft, easily eroded sediment, usually where vegetation is sparse and rainfall is intense but seasonal. In India the Chambal valley is the textbook case, its beehad formed in thick alluvium.
