Desertology (knowledge of the desert)

Desert or salt marsh is a land in which according to the profusion of salt no crop can be farmed or cultivated. Of course in some regions some kinds of plants live, but these plants are not crops and they are not edible but mostly they are used for industrial purposes or they are used to feed animals like goats and camels. In other word desert is a place with no water or greenery. Anyway, a huge part of Iran is consisted of deserts like Loot Desert , Yazd desert Tabas desert etc. each of which includes smaller deserts in itself. Some tourists travel to these deserts just for enchanting and delightful visions. These people take refuge in the mysterious silence of the desert, haunting the traditional mud-made houses or Caravanserais, watching the stars (as desert is the place to watch the sky and the stars far from dust layers of the cities etc.) and going up and down the soft sandy hills, to have a joyful and calm experience. Others however, prefer a more adventurous journey as the sandy hills, roads and plains of the desert are very convenient for racing rallies and other exciting events.
