Which feature is formed by wind-blown sand and serves as a shoreline protector?

Explanation:
Dunes form when wind-driven sand accumulates and is stabilized by vegetation, creating elevated piles along the shore. These raised sand features act as natural barriers that absorb and break up wave energy, reducing erosion and shielding inland areas from storm surge. They also trap more sand, helping to rebuild beaches after storms, and can migrate inland as conditions change, keeping pace with sea-level rise. Lagoons are shallow bodies of water behind barrier beaches, peat deposits come from accumulating and decaying vegetation in waterlogged soils, and barrier flats are flat coastal areas not primarily built by wind-blown sand nor serving the same protective role as dunes.
