A dune is a hill or ridge of sand piled up by the wind, in a desert or near the sea. tree →

In the lessons

In geography and science lessons, wind moves sand and builds dunes; dunes slowly move and change shape. On beach trips, dunes protect the land from the sea, so we stay on paths. Phrases: «sand dune», «sand dunes», «behind the dunes».
