The asymmetric shape of a yardang results from what?
Answer and explanation
Correct answer: स्थिर प्रमुख पवन दिशा और विभेदक घर्षण
The governing concept is wind erosion under differential resistance. A yardang is carved from weakly consolidated material by persistent winds, commonly becoming streamlined in the prevailing wind direction. Softer layers or projections are abraded and removed faster than harder parts, producing unequal slopes and an asymmetric profile. Uniform river deposition, groundwater solution, and glacial-moraine pressure do not explain this aeolian form, so option A is correct.
