Desert Sand - Sandatlas
To describe a desert sand, we first have to make clear what we are talking about. When we imagine desert sand, we probably think of sand dunes. That is what I am writing about here although dune fields cover only about 20 percent of modern desert areas. Sand dune in Sahara (Morocco). Note how wind is blowing sand grains off the crest of the dune.
