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

Chambal Ravines are formed primarily by gully erosion, which is the advanced stage of soil erosion where water creates deep channels. The Chambal region's highly erodible soil, coupled with the monsoon climate and historical deforestation, has made it susceptible to severe gully erosion, creating the characteristic badland topography of ravines. Splash erosion is the initial stage, sheet erosion is the removal of thin soil layers, and rill erosion creates small channels that can evolve into gullies.
