How is a capture elbow identified after river capture?
Answer and explanation
Correct answer: By an unusual sharp bend in the stream course
The governing concept is stream capture, in which a vigorous stream diverts the headwaters of another drainage system. At the point where the captured stream changes direction toward its new outlet, the channel commonly makes an abrupt, unusual bend. This feature is the capture elbow, so option B is correct. Beach ridges, stalactites, and dune horns are unrelated coastal, karst, and aeolian features.
