You will realise that almost all the deserts are confined within the 15 degree to 30 degree parallels of latitude north and south of the equator. They lie in the trade wind belt on the western parts of the continents where Trade winds are off-shore.
See Article History Alternative Title: Desierto de Atacama Atacama Desert, Spanish Desierto de Atacama, cool, arid region in northern Chileto miles 1, to 1, km long from north to south.
To the north the desert continues to the border of Peru. A line of low coastal mountains, the Cordillera de la Costa, lies to the west of the desertand to its east rises the Cordillera Domeyko, foothills of the Andes.
The desert consists mainly of salt pans at the foot of the coastal mountains on the west and of alluvial fans sloping from the Andean foothills to the east; some of the fans are covered with dunesbut extensive pebble accumulations are more common. The coastal chain hovers around 5, feet 1, metres or so The atacama desert essay elevation with individual peaks reaching to 6, feet 2, metres.
There is no coastal plain. Through much of their extent the mountains terminate abruptly at the sea in cliffs, some of them higher than 1, feet metresmaking communication difficult between the coastal ports and the interior. In the interior a raised depression extends north and south and forms the high Tamarugal Plain at an elevation of more than 3, feet metres.
Farther to the east in the western outliers of the Andes, preceded by the Cordillera Domeykothere are numerous volcanic cones, some exceeding 16, feet 4, metres in elevation. Dry subsidence created by the South Pacific high-pressure cell makes the desert one of the driest regions in the world.
Along the coast the aridity is also a consequence of the Peru Humboldt Currentwhich is characterized by upwelling the upward movement of cold water from the depths of the ocean ; the resulting cold water at the surface causes a thermal inversion—cold air at sea level and stable warmer air higher up.
This condition produces fog and stratus clouds but no rain. Rains fall in Iquique or Antofagasta only when powerful southern fronts break into the subsidence area. Temperatures in the desert are relatively low compared with those in similar latitudes elsewhere.
Atacama DesertAtacama Desert, Chile. For much of the 19th century, the desert was the object of conflicts among Chile, Bolivia, and Peru because of its mineral resources, particularly sodium nitrate deposits located northeast of Antofagasta and inland from Iquique.
Much of the area originally belonged to Bolivia and Peru, but the mining industry was controlled by Chilean and British interests, which were strongly supported by the Chilean government. From the War of the Pacific —83Chile emerged victorious.
Nitrate deposits in the central depression and in several basins of the coastal range were systematically mined after the midth century.
Ports were built at Iquique, Caldera, Antofagasta, Taltal, Tocopilla, Mejillones, and, farther north, Pisagua, and railroads penetrated the mountain barriers to the interior.
The development of synthetic methods of fixing nitrogen have since reduced the market to a regional one. Some sulfur is still mined in the high Cordillera.
Lemons are grown at Pica, and a variety of products are cultivated on the shores of the salt marshes at San Pedro de Atacama. At Calama, near Chuquicamata, water from the Loa River irrigates potato and alfalfa fields.

The extreme aridity of the climate and unusual mineralogy of the regolith in the Atacama region is of considerable interest because of its value as an analogue to the Martian surface.
The Salar de Atacama (salt flat) is a large salt-covered basin floor lying between the Coastal Cordillera and the Andean Cordillera at the north end of the Atacama Desert (Dransart ).
To the east of the Salar de Atacama the excessively high elevations of the western Andes is called the Puna region.
