About this work
Sand dunes commonly form when particles that are being moved around by the wind find a natural barrier to accumulate and build a hill-like formation. Scientists study dunes because their shape and size can give us valuable information about the wind directions and speeds in current and past climates. For instance, barchan dunes are crescent-shaped, and they form when the wind blows mainly from one direction (perpendicular to the crescent long edge).
