The long axis of a longitudinal or seif dune is related to what?
Answer and explanation
Correct answer: हवा की परिणामी दिशा के लगभग समानांतर
The governing concept is the orientation of linear aeolian dunes. A longitudinal, or seif, dune is a long, narrow ridge that generally develops parallel to the resultant direction of two or more effective wind flows. Sand is transported along the ridge rather than forming a crest across the wind. River depth, sea-tide opposition, and circular glacial cracks are unrelated, so option A is correct.
