Sand dunes that are at right angles to the wind are called Transverse Dunes. They form with weak winds and an abundant supply of sand.
Long sand ridges oriented nearly parallel to the prevailing wind are called sand dunes. They are formed by the deposition of sand carried by the wind and are common in deserts and coastal areas.
Transverse dunes are long sand ridges that are oriented at right angles to the prevailing wind direction. They form when wind blows sand over a stationary object, like a plant or rock, causing the sand to accumulate into a ridge perpendicular to the wind direction.
it formed from ancient sand dunes.
Barchan dunes are solitary crescent dunes formed on a flat, hard ground with limited supplies of sand and vegetation. Transverse dunes are a series of long ridges that are found in areas that have a lot of sand but sparse vegetation.
Sand dunes are a land feature that forms from the deposition of sand by the wind. As wind blows sand particles across a landscape, they accumulate and form distinctive mounds or ridges called sand dunes.
Loess blankets a broad area; sand dunes aer mounds or ridges.
Barchan dunes are crescent-shaped with horns pointing downwind. Parabolic dunes have a U-shape with horns pointing upwind. Transverse dunes are long ridges perpendicular to the wind direction. Star dunes are complex, multi-crested dunes formed by variable wind directions.
Huge piles of sand are called sand dunes. Sand dunes typically form in deserts or coastal areas where there are strong winds that shape and move the sand into these large structures.

Hills of windblown sand, also known as sand dunes, are formed by the accumulation of sand particles carried by the wind. These dunes can vary in size and shape, with the movement of sand being influenced by factors such as wind direction and speed. Sand dunes play important roles in coastal protection and ecosystem dynamics.
