In all the planet, 35% of the surface of the
continents (50 million squared kilometros) are formed by barren
regions. In Azizia, Libya, was registered the biggest temperature of the globe: 59 C. But in all the
deserts are of sand and heat. In Gobi, in the Mongólia, the cold arrives at the -19 C. In Antarctica and in the Groelândia the deserts meet absolute, regions where water in liquid state inexists. In the hot
areas of the Land it is the complex system of atmospheric circulation that create gigantic responsible airflows for the
formation of multiple dune drawings. E, even so these sand mounts are the classic representation of the image of the deserts, them represent only 15 20% of its landscape. But the Arabian Desert, in the Middle East, arrives to have 30% of its area covered for
dunes. In accordance with researchers, the study of these areas make possible the understanding of the formation of the winds that blew have 120 million years. E helps to rescue lost details of the history of the continents.
