Deposits of sand at the ocean's edge widen beaches and coastal areas by accumulating material carried by waves and currents. This process, known as sediment deposition, occurs when water slows down and loses energy, allowing sand particles to settle. Over time, these deposits can create wider shorelines, enhancing habitats for various marine and terrestrial species while also influencing coastal erosion and landscape changes.

The wind carrying sand grains deposits the sand when the wind's velocity decreases, or when an obstacle interrupts the wind flow. This causes the heavier sand grains to settle and accumulate, forming sand dunes.
One descriptor would be 'an aeolian deposit. Which means a deposit caused by wind. An alternative would be the name Loess, which means the same thing. Downwind of a desert region, Loess deposits may be many tens of metres in thickness.
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
Aeolian deposits can be smooth sand sheets that can resemble a desert floor. They can be mobile sands that form active sand sheets or rugged vegetated sand sheets
The types of wind deposits include dunes, loess deposits, and sand sheets. Dunes are mounds of sand shaped by wind, while loess deposits consist of fine-grained sediment deposited by wind. Sand sheets are large areas covered with wind-blown sand.
Sand dunes and loess deposits are two types of deposits formed by wind erosion and deposition. Sand dunes are hills of sand that form in areas with strong winds, while loess deposits are fine, wind-blown sediment that accumulates over time to create thick layers of fertile soil.
Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.
