Barchan dunes are characterized by?

Explanation:
Barchan dunes form in desert settings where wind is strong and mostly from one direction and sand supply is limited. Their shape is crescent-like, with the horns (tails) extending downwind; the slip face sits on the inside of the crescent. Sparse vegetation is typical because the harsh, arid conditions limit plant growth, which also helps these dunes stay mobile rather than being anchored by vegetation. This combination—unidirectional wind, limited sand, and an arid, sparsely vegetated environment—produces the characteristic crescent shape with leeward tails, making the description accurate.
