The Correct Option is A

Solution and Explanation


Step 1: Concept

Soil erosion occurs in stages, starting from raindrop impact to the formation of large gullies.

Step 2: Meaning

The term describes the process where thin, horizontal layers of topsoil are stripped away across a wide area.

Step 3: Analysis

Splash erosion is the initial impact of droplets, while rill and gully erosion involve concentrated channels. Sheet erosion is often "silent" because it removes soil uniformly without leaving deep scars initially.

Step 4: Conclusion

The removal of a uniform layer is specifically defined as sheet erosion.
