  6. 6. 6 1. Erosion forms  Explanation: All these erosion forms occur for the same thing: deflation. Deflation happens when the desert lose a patch of protective vegetation, allowing strong winds carried the sand and form a depression that destroys the soft materials leaving the hard materials, creating different erosion forms.

  11. 11. 2. Sedimentary forms  The sedimentation and the dune correlative constructions are those that express more commonly the morfophogenesis of the wind in the arid domains and coastal sectors, for the extension of the spaces that they cover, for the diversity of types and for the considerable dimensions that reach in occasions. They are in the habit of the warehouses of sand classifying, for his size, in three types. 11
  12. 12. 12 3. Transport forms  2.1. Deflation  Is a displacement of individual particles. It works until the saturation of the wind causes it to crash. When attacked superfecie includes excerpts too heavy for the wind is produced which leads to a concentration on gravel and rocky cover songs, which protect the underlying material. When the area affected has mobilized fragments are excavated basins and closed depressions and large, that in arid enviroments may be large.
  13. 13. 13 3. Transport forms  3.2. Supension  Suspension affects very fine particles such as sand and dust. Remain in the air because the updrafts are stronger than gravity. Are elevated to several meters high and end up falling slowly. Sometimes they can be suspended and be transported thousands of kilometres.
