What is another word for drift-sand?
Pronunciation: [dɹˈɪftsˈand] (IPA) 
Drift-sand, also known as sand drift, refers to the movement of sand particles by wind. Synonyms for drift-sand include sand dunes, sand hills, sand drifts, and sand piles. Sand dunes are formed when loose sand is blown by the wind and accumulates over time, creating mounds of sand that can reach tens of meters in height. Sand hills, on the other hand, are smaller than sand dunes and are usually found in coastal areas. Sand drifts and sand piles refer to smaller accumulations of sand that are dispersed across a larger area, typically on beaches or in deserts. All of these synonyms describe the dynamic and ever-changing nature of sand as it is carried by the wind.
