The prevailing winds are from the east and the tall Andes Mountains prevent any moisture from the Atlantic Ocean and Amazon basin from reaching the area. The Coastal Range prevents any moisture from the Pacific from reaching the Atacama. Rain does fall in some parts of the desert but it amounts to little more than a sprinkle.
The Atacama and the Antarctic Deserts rarely receive precipitation.
By moving to the Atacama desert where it never rains.
Chile, in South America in the Atacama Desert and Antarctica are the driest deserts on earth.
Since it rarely rains in the Atacama, nearly all weathering would be physical weathering caused by the wind.
It usually rains somewhere in the Atacama every year. The amount is little more than a sprinkle and some areas of the desert have not experienced any rainfall in historic times.
Antarctica and the Atacama Desert receive little rainfall.
The Atacama desert is not very humid at all. The Atacama desert is the driest place on the earth. Some locations, however, receive a marine fog known locally as the camanchaca, that provides sufficient moisture for hypolithic algae, lichens and even some cacti to grow. Some animals, particularly insects, are able to harvest this moisture which allows them to survive in this harsh climate.However, there are some areas in the Atacama which receive little rainfall each year but maintain a high humidity due to the proximity of the Pacific Ocean. Arica, for example, receives less than 1 mm of precipitation per year but has an average humidity of nearly 75%.
The Atacama receives virtually no rain as opposed to other deserts around the world that do receive some precipitation. There are some parts of the Atacama that have not measured any rain since records have been kept, going back over 400 years.
The Atacama Desert is dryer than the Sahara Desert. The Atacama is considered the driest desert in the world, receiving very minimal precipitation, while the Sahara does receive occasional rainfall in some regions.
The Atacama Desert is one of the few deserts on Earth that does not receive any rain.Another Answer:The above statement is not exactly true. While there are areas of the desert that have not measured any rainfall in historic times, some areas may receive a millimeter or two of precipitation each year. Generally, the Atacama receives less than 1/4 inch of rain per year.
In some areas of the Atacama that receive dense fog from the Pacific Ocean, they have conducted experiments with equipment that can condense liquid water from fog with some success.
Both the Antarctic Desert and the Atacama Desert are exceedingly dry and receive virtually no precipitation.
