The boundless sea of sand is a familiar desert landscape. It is hard to imagine a place less adapted for life than this. And yet, even here animals and people live, accustomed not only to the unimaginable heat, but also to the changeable disposition of this wasteland.
And if we talk about the desert, then we should not lose sight of such a thing as a dune. What is a dune, it would seem, is easy to imagine. But even he can hold in himself amazing secrets, the knowledge of which is extremely important for survival in the desert.
So, dune - what is it?
First, let's look at the information that the geographical community gives us. So, based on their data, the dune is a huge accumulation of sand, which subsequently forms hills or small mountains. The dune always has a curved shape, somewhat reminiscent of a sickle or crescent. But how is a dune formed? What is he, and by what laws does he exist?
In reality, everything is very simple. The dune is formed due to the breath of wind, which distills grains of sand from one place to another. This action resembles the movement of water in the oceans, with its ripples and waves. And if after the end of the wind the surface of the sea becomes smooth again, then in the desert everything is completely different. When calmness sets in, everything here freezes in place, as if time has frozen and does not want to move on.
Sand Wasteland Life
People living in desert areas are often forced to lead a nomadic lifestyle. Indeed, even when their houses are within the same oasis, they still somehow need to get food, resources and medicines. Therefore, from time immemorial, they have been engaged in trade between settlements, doing many kilometers long routes through the desert.
That is why they know well what a dune is, and how insidious it can be. Indeed, unlike an ordinary hill, the dune does not stand in one place. Under the influence of strong winds, he wanders from place to place, which greatly complicates the life of trackers. That is why desert residents from early childhood study the laws by which dunes move. Otherwise, how can they then master the vast expanses of the desert?
Dunes: Harsh and slightly dramatic
But how do the inhabitants of the East see the dune? What is a dune for them: a stern enemy or a silent companion on the way? Probably, it all depends on the person himself and on how he looks at the world. After all, some complain about fate, while others accept its challenges with their heads held high.
The same goes for dunes. Someone sees enemies in them, and someone finds them beautiful. After all, when the sand under your feet rapidly crumbles down, it seems that the dunes begin to sing. And this song captivates those who gave their heart to the endless horizons of the desert.
