Identify the correct order of the processes of soil erosion from the following:
- ASplash erosion, Sheet erosion, Rill erosion, Gully erosionCorrect
- BSheet erosion, Splash erosion, Gully erosion, Rill erosion
- CRill erosion, Gully erosion, Sheet erosion, Splash erosion
- DGully erosion, Rill erosion, Sheet erosion, Splash erosion
Explanation
The correct order represents the progressive stages of soil erosion by water, moving from the impact of a single raindrop to the formation of large ravines.
First is Splash erosion, where raindrops hit bare soil and scatter soil particles.
Second is Sheet erosion, which occurs when a thin layer of topsoil is removed uniformly over a large area by surface runoff.
Third is Rill erosion, which happens when the running water concentrates into narrow, shallow channels or fingerlike streaks.
Fourth is Gully erosion, the final stage where rills deepen and widen into large channels that cannot be removed by normal tillage.
Therefore, the sequence follows the increasing intensity and scale of the erosion process.
