In which direction do the horns of a barchan dune point?
Answer and explanation
Correct answer: In the direction of prevailing wind
A barchan is a crescent-shaped dune formed where wind blows mainly from one direction and sand supply is limited. Its convex, steeper slip face faces downwind, while the two pointed horns extend farther in the direction of movement. Thus the horns point downwind, or with the prevailing wind. River and glacial directions are irrelevant to this aeolian landform, so option D is correct.
