What is the process from sheet wash to rill formation on a slope?
Answer and explanation
Correct answer: Spread surface flow becomes concentrated into small streams and cuts shallow channels
Sheet wash is a thin, relatively widespread layer of runoff moving over a slope. Small irregularities, soil texture, and decreasing infiltration make the flow concentrate into narrow paths. These concentrated threads have greater erosive power and cut shallow channels called rills. With continued runoff and enlargement, rills may develop into gullies. Thus option A explains the sequence; the other options describe unrelated processes.
