One of the facts about Atacama desert that leave us astonished is its climate. The place is pretty cold despite being the driest desert and the temperature ranges between 0°C to 25°C. The annual rainfall in this area is less than 0.004 inches/0.01cm of rain per year. Since the desert lies between Andes mountain in the east and Chile coast to the west, this region has rain shadow effect and is deprived of moisture.
Water Bodies

In the distant past, sometimes during rains, a few water basins were formed throughout the Andes, which got transformed into lakes. With passage of time, lakes started drying up, leaving behind concentrated salty water.
Snow and Fog

The scientific causes related with its geographic location, makes it the driest desert in the world. A rain shadow region is present on the leeward side of the Andes mountain and Chile coast.

Other factors contributing the dry climate are, anticyclone of the Pacific ocean, marine fog shadow, absence of rainfall, and presence of permafrost at high altitudes.
