Why does a beheaded stream form after river capture?
Answer and explanation
Correct answer: Because its upper drainage is captured by a stronger neighbouring stream
The correct answer is A. River capture, or stream piracy, occurs when an actively eroding neighbouring stream breaches a divide and diverts the headwaters of another drainage system. The captured upper course then flows into the pirate stream, leaving the former downstream channel with reduced discharge and no original headwaters. This shortened or deprived channel is called a beheaded stream. The other choices describe unrelated coastal, glacial, or aeolian processes.
