Why can a star dune become very high?
Answer and explanation
Correct answer: Multidirectional winds keep piling sand in a central area
A star dune develops where winds arrive from several directions over a substantial supply of sand. The different wind directions build intersecting ridges around a central peak, and sand can accumulate rather than being transported consistently along one axis. Continued supply and changing wind patterns allow the central mound to grow high and complex. Thus option A is correct; river erosion, glacial abrasion, and karst solution are unrelated processes.
