What are the four main shapes of dunes?
The four main shapes of dunes are barchan, transverse, longitudinal, and star dunes. Barchan dunes are crescent-shaped and form in areas with limited sand supply and consistent wind direction. Transverse dunes are larger, ridge-like formations that develop perpendicular to the wind direction. Longitudinal dunes are elongated and form parallel to the prevailing wind, while star dunes have multiple arms and form in areas with variable wind directions.
