उत्तर
-
Crescent-shaped: Barchans are moon-shaped dunes with their horns (tips) pointing in the direction of the wind.
-
Migration: They are live dunes that advance steadily in the direction of the prevailing wind, causing them to move over time. This migration can be a threat to desert life, as they may bury vegetation and even settlements.
These characteristics make Barchans easily recognisable, and they are commonly found in deserts like the Sahara.
