*** About Sand Dunes: Sand dunes are dynamic natural structures formed by the movement and accumulation of sand due to wind and occasionally water. They can be found in various environments across the globe, from coastal and riverside regions to vast desert expanses. Dunes play a critical role in environmental and ecological systems by acting as barriers against wind and water erosion. They also provide a unique habitat for a variety of flora and fauna specially adapted to these arid conditions. The formation of sand dunes is a fascinating geological process that involves the transport and deposition of sand grains, a process governed by the wind's direction and strength, and the sand’s characteristics.
