The secondary dune is the sand dune behind the primary dune.
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.
Secondary forces, such as erosion, weathering, and deposition, create various landforms such as canyons, valleys, caves, sand dunes, and deltas. These forces sculpt the earth's surface over time by breaking down rocks, moving sediments, and reshaping the landscape through natural processes.
Mounds of loose sand are called sand dunes. They are formed by the accumulation of sand carried by the wind and can vary in size and shape. Sand dunes play a vital role in coastal protection and as habitats for various plant and animal species.
Wind erosion and deposition may form sand dunes and loess deposits.

There are only two sand dunes in Michigan. The two sand dunes are Sleeping Bear Dunes and Sliver lake sand dunes.
Fore dunes and back dunes but mostly fore dunes.
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.

Moving dunes is what is in my book...
Florida has so many dunes on every single beach! :0)
Dunes are not stationary because they move with the wind.
