How are transverse dune formed?

Transverse dunes are formed by strong, consistent winds blowing across an area with a limited supply of sand. The wind transports sand particles, accumulating them on the downwind side of obstacles, such as vegetation or small topographical features. As sand continues to collect, it creates long, linear ridges that are oriented perpendicular to the prevailing wind direction. The shape and size of these dunes can vary based on the wind strength and sand availability.
