How can a dune formed by multidirectional winds be identified?
Answer and explanation
Correct answer: High star dune with several arms
The governing concept is dune morphology controlled by wind direction. When winds blow from several significant directions, sand is transported toward and around a central accumulation from different sides. The result is a steep, pyramidal or star-shaped dune with several radiating arms or ridges. Therefore option B is correct. A long single axis is more typical of a linear dune, while a pothole is fluvial erosion and a limestone column is a karst feature.
