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. 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

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.

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.
