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.
Earthquakes generate both transverse and longitudinal waves.
Yes sand dunes are caused by winds
yes, sand dunes are deposited by wind
Dunes are a natural barrier and therefore minimize erosion.
Plants can help stabilize sand dunes and prevent them from moving.
D) all above barchan dunes are arc-shaped and are also known as crescentic. transverse dunes are perpendicular to the wind and are usually built upon already-existing sand mounds star dunes are radially symmetric pyramidal mounds.
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.

That they are not called the same.duhhh
Barchan dunes are crescent-shaped dunes that are formed by winds blowing consistently in one direction. These winds are typically strong and blow a constant supply of sand, causing the dunes to migrate downwind.
A barchan is an arc-shaped sand ridge comprised of well-sorted sand.
A barchan dune has a crescent shape with horns pointing downwind and forms in areas with limited sand, while a parabolic dune has a U-shape with the horns pointing upwind and forms in areas with abundant sand. Additionally, barchan dunes are individual and migrate due to wind direction, while parabolic dunes are stationary and often found in coastal regions.

you need to sort out your grammer, because last time I checked it was "were".
Barchan dunes are the crescent-shaped sand dunes commonly observed on Mars. They have a characteristic shape with a gentle slope facing the prevailing wind direction and a steeper slope facing away from the wind. Barchan dunes are formed by the movement of wind-blown sand.
Transverse dunes are sand dunes formed across the direction of the winds that prevail in a given area. This is the "normal" way dunes form when winds blow sand across open areas. A link can be found below for more information and to view images.
