The Sleeping Bear Dunes, located in Michigan, are dynamic and constantly changing due to natural forces like wind and water. While the dunes can shift significantly over time—sometimes moving several feet per year—the exact speed of movement varies based on environmental conditions. Factors such as wind direction, speed, and moisture levels play a crucial role in how quickly the dunes can migrate. Overall, it's a gradual process rather than a rapid one.
Dunes are not stationary because they move with the wind.
Sand dunes move down wind. A simple example: if the prevailing wind is from the west, the dunes will mainly move towards the east.

Yes. Dunce move in the direction of the current or wind.
wind and storms cause the dunes to move by moving around the individual sand grains when the dunes get too large the 15 mph winds will cause them to collapse and thus it has moved.

The wind causes movement
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.
No way to tell, sand dunes move every time a wind springs up.
they dont have periods.
In the direction of the prevailing wind. In geology, unidirectional cross-bedding can be preserved in sandstones, showing the procession of dunes over time.
