The long direction of a yardang is generally parallel to what?
Answer and explanation
Correct answer: Prevailing wind direction
A yardang is a streamlined, elongated ridge carved mainly by wind abrasion and deflation in an arid region. As wind repeatedly attacks the weaker material, it produces grooves and ridges aligned with the dominant airflow. Therefore, the long axis of a yardang is generally parallel to the prevailing wind direction. River channels, coastlines, and lateral moraines are formed by different agents and do not explain this alignment.
