The sand collects debris from the sea and they began to pile up. More sand piles up so the mound becomes a sand dune. Plants like Marram grass hold together sand dunes.
The movement of dunes is called dune migration. If the wind usually blows from the same direction, dunes will move downwind. Dune migration occurs as sand is blown over the crest from the windward side and builds up the slipface. In mostly level areas, dunes migrate until they reach a barrier. To prevent dunes from drifting over highways and farm land, people often build fences or plant grasses, trees, and shrubs.
the top of a sand dune is called the crest of the dune.
