What is the main difference between rill and gully erosion?
Answer and explanation
Correct answer: Rills are small shallow channels, while gullies are deeper and more developed channels
The governing concept is runoff erosion on a slope. When rainwater flows as concentrated surface runoff, it first cuts small, shallow channels called rills. If runoff continues and removes more soil, these channels enlarge, deepen, and become gullies that are harder to erase by normal cultivation. Thus option B correctly states the size and development difference; the other options reverse the terms or confuse erosion with glacial or marine deposition.
