Dune

“Dune” refers to a mound or ridge of sand formed by the wind, typically found in deserts or near the shoreline. Dunes are shaped by the movement of sand particles due to air currents, and they can vary in size and structure, including features like ripples and ridges. There are various types of dunes, such as barchan, parabolic, and linear dunes, each characterized by distinct shapes and formation processes. Dunes play a significant role in coastal and desert ecosystems, affecting local wildlife and vegetation. They also serve as natural barriers against wind and water erosion. In a broader context, “Dune” is often associated with the science fiction novel by Frank Herbert, which explores themes of ecology, politics, and philosophy on the desert planet of Arrakis, also known as Dune, but this is related to its cultural impact rather than its primary definition.
