Which one of the following types of erosion is responsible for the formation of Chambal Ravines?

Answer: (d) Gully

Deep gully erosion carved the Chambal ravines.

The idea

Ravines form when runoff repeatedly deepens and branches large erosion channels. Their size distinguishes them from tiny rills and the thin removal of a soil sheet. The resulting maze of steep channels is often called badland topography.

Rain falls on exposed, erodible ground → Runoff gathers into channels → Channels deepen into gullies → Headward erosion extends the gullies → Sides collapse and branches develop → An interconnected ravine landscape forms

Why the others are wrong

(a) Splash erosion is the first, smallest stage.

(b) Sheet erosion removes thin layers.

(c) Rills are small channels.

Elimination technique

Splash detaches particles and sheet erosion removes a shallow layer; rills are small channels. Deep ravines require the larger channel-cutting stage, so choose gully erosion.

Chambal rises near Janapav in Madhya Pradesh and joins the Yamuna in Uttar Pradesh. The Betwa and Ken are other right-bank tributaries of the Yamuna. The National Chambal Sanctuary protects a stretch shared by Madhya Pradesh, Rajasthan and Uttar Pradesh. Ravine control uses vegetation, runoff management and carefully placed barriers.
