The illusion of a grand desert almost perfect in the dunes of the Canary Islands. Indeed this is not completely wrong. The sand deposited here comes from the African Sahara desert and it arrived via geological sky cargo. Intense sandstorms are frequent over Earth’s largest desert. Tiny sand grains are transported high up into the atmosphere. Transported by an northerly air stream red sand deposits occur over the European Alps, causing blood-snow. Transported southwesterly the sand dust is deposited over the Canary Islands. These dust clouds are composed of aerosols that are frequently visible on satellite images. This aerosol even is the main fertilizer of the Brazilian rain forest.
