In the progression of water erosion on an agricultural field, the erosion stage that directly succeeds sheet erosion and creates small, distinct micro-channels that can still be erased by conventional tillage implements is:
Options:
(A) Splash erosion
(B) Rill erosion
(C) Gully erosion
(D) Stream bank erosion
Answer Key:
B
Step-by-Step Solution & Explanation
Rill erosion is the intermediate phase of water erosion wherein overland runoff concentrates in numerous small finger-like incisions (rills). Unlike gullies, rills are small enough to be easily smoothed out during routine seedbed preparation.
