Question

Water erosion follows the sequence:
(A) Ravine
(B) Sheet
(C) Splash
(D) Rill
(E) Gully

• A. (A), (B), (C), (D), (E)
• B. (C), (B), (D), (E), (A)
• C. (B), (A), (D), (C), (E)
• D. (C), (B), (A), (E), (D)

Hint:

Understanding erosion stages helps in soil conservation and planning anti-erosion measures.

Answer 1

The Correct Option is B

The stages of water erosion start from splash erosion (raindrop impact), followed by sheet, rill, gully, and finally ravine erosion.

Answer 2

Progressive channelisation logic: Water erosion intensifies as flowing water becomes increasingly concentrated. It begins with the direct impact of raindrops dislodging individual soil particles, splash erosion.
As dislodged particles are carried by a thin, uniform film of water across the surface, this becomes sheet erosion, still without visible channels.
As flow paths merge, water concentrates into small, shallow channels that can still be smoothed out by normal tillage, rill erosion.
Left unchecked, rills deepen and widen into channels too large for tillage to remove, gully erosion.
Finally, gullies that continue to enlarge over years become deep, permanent, un-reclaimable channels, ravines.
This energy-and-channel-size progression gives splash, sheet, rill, gully, ravine, matching (C), (B), (D), (E), (A).
