Desert dunes typically form in arid regions and are characterized by their sandy composition and unique shapes sculpted by wind.

Sand dunes are fragile because they are made up of loose particles that are easily shifted by wind and water. Human activities, such as trampling, off-road vehicles, and development, can disrupt the stability of sand dunes and lead to their degradation. Once the protective vegetation cover is removed, sand dunes become vulnerable to erosion and can lose their characteristic features.
